Adventure Time

Premise

Adventure Time follows the adventures of a boy, named Finn the Human, and his best friend and adoptive brother, Jake the Dog, who has magical powers to change shape and size at will. Pendleton Ward, the series' creator, describes Finn as a "fiery little kid with strong morals". Jake, on the other hand, is based on Tripper Harrison, Bill Murray's character in Meatballs. This means that while Jake is somewhat carefree, he will "sit [Finn] down and give him some decent advice if he really needs it". Finn and Jake live in the post-apocalyptic Land of Ooo, which was ravaged by a cataclysmic event known as the "Mushroom War", a nuclear war that destroyed civilization a thousand years before the series' events.

Throughout the series, Finn and Jake interact with major characters, including Princess Bubblegum, the sovereign of the Candy Kingdom and a sentient piece of gum; the Ice King, a menacing but largely misunderstood ice wizard; Marceline the Vampire Queen, a thousand-year-old vampire and rock music enthusiast; Lumpy Space Princess (Pendleton Ward), a melodramatic and immature princess made out of "lumps"; BMO, a sentient video game console-shaped robot that lives with Finn and Jake; and Flame Princess (Jessica DiCicco), a flame elemental and ruler of the Fire Kingdom.

Development

Concept and creation

According to series creator Pendleton Ward, the show's style was influenced by his time attending the California Institute of the Arts (CalArts) and his experiences working as a writer and storyboard artist on The Marvelous Misadventures of Flapjack, a series that ran on Cartoon Network from 2008 until 2010. In an interview with Animation World Network, Ward said he strove to combine Adventure Time's subversive humor with "beautiful" moments, using Hayao Miyazaki's film My Neighbor Totoro as inspiration for the latter. Ward has also named Home Movies and Dr. Katz, Professional Therapist as influences, largely because both shows are "relaxing" and feature "conversational dialogue that feels natural [and is neither] over the top [nor] cartoony and shrill".

The series traces its origins to a seven-minute, stand-alone animated short film of the same name (this short was later identified as the show's pilot post factum). Produced by Frederator Studios, the short was created by Ward almost entirely by himself, and its production concluded in early 2006. It was first broadcast on Nicktoons Network on January 11, 2007, and was re-broadcast as part of Frederator's anthology show Random! Cartoons on December 7, 2008. After its initial release, the video became a viral hit on the Internet. Frederator then pitched an Adventure Time series to Nicktoons Network, which rejected it five times. When Nicktoons' rights to commission a full series expired, Frederator pitched it to other channels. One of the studios that Frederator approached was Cartoon Network, which was interested in producing a full series, but would commit to a deal only if Ward could prove the pilot "wasn't a one-hit wonder". Rob Sorcher, the chief content officer at Cartoon Network, was influential in getting the network to take a chance on the show; he recognized the series as "something that felt really indie ... comic book-y [and] new".

Cartoon Network asked Ward to submit a sample script for their consideration, but Frederator convinced him to rough out a storyboard instead, as "a board would give a better sense of what was on Pen's mind", according to Frederator's vice president Eric Homan. Ward and his college friends Patrick McHale and Adam Muto (who both would go on to take significant roles in the series' production) began developing ideas, all the while concentrating on "keep[ing] the good things about the original short [while also] improv[ing] on" them. The group's first product was a rough storyboard featuring Finn and Princess Bubblegum going on a spaghetti-supper date. After Cartoon Network rejected the initial story, Ward, McHale, and Muto storyboarded "The Enchiridion!" to emulate the original Nicktoons short. This tactic proved successful, and in August 2008, Cartoon Network approved a first season, which was produced by Cartoon Network Studios. "The Enchiridion!" was the first episode to enter into production.

Production

Ward—a self-professed fan of ambivalent emotions, such as feeling "happy and scared at the same time"—has called the show a "dark comedy". He has also cited the fantasy role-playing game Dungeons & Dragons—of which many of the show's writers are devotees—as an inspiration for the show. In the United States, the series is rated TV-PG; Ward said he never wanted to push the boundaries of the PG rating, noting in an interview with Art of the Title that he "never really even thought about the rating ... we don't like stuff that's overly gross. We like cute stuff and nice things". Ward intended the show's world to have a coherent physical logic, and although magic exists in the story, the show's writers tried to create an internal consistency in the characters' interactions with the world.

In an interview with The A.V. Club, Ward said the show's writing process usually began with the writers telling each other what they had done the previous week to find something humorous to build on. He also said, "A lot of the time, if we're really stuck, we'll start saying everything that comes to our mind, which is usually the worst stuff, and then someone else will think that's terrible but it'll give him a better idea and the ball just starts rolling like that". Because of the busy schedule of writing and coordinating a television series, the writers did not have time to play Dungeons and Dragons, but they still wrote stories they would "want to be playing D&D with". Sometimes, the writers and storyboard artists convened and played writing games. One game that was often used is called exquisite corpse, which one writer starts a story on a sheet of paper, and another writer tries to finish it. However, while a few episodes (such as the fifth-season episode "Puhoy" and the sixth-season episode "Jake the Brick") have been generated using this game, Ward has said that "the ideas are usually terrible". Former storyboard artist and creative director Cole Sanchez said episode scripts are either created by expanding the good ideas produced by these writing games, or are based on an idea proposed by a storyboard artist in the hope it can be developed into an episode.

After the writers pitched stories, the ideas were compiled onto a two-or-three-page outline that contained "the important beats". The episodes were then passed to storyboard artists (often called "boarders"). While many cartoons are based on script pitches to network executives, Cartoon Network allowed Adventure Time to "build their own teams organically" and communicate using storyboards and animatics. Rob Sorcher said this novel approach was sanctioned because the company was dealing with "primarily visual people", and that by using storyboards, the writers and artists could learn and grow "by actually doing the work". The storyboard artists generally worked on an episode in pairs, independent from other storyboarders, which, according to freelance writer David Perlmutter in his book America Toons In, countered creative ennui and prevented episodes from being "alike in either content or tone". The storyboard artists were given a week to "thumbnail" (roughly sketch out) a storyboard and fill in the details complete with action, dialogue, and humor. The series' showrunner and his creative directors then reviewed the storyboard and made notes. The artists were then given another week to implement the notes and to clean up the episode. Storyboard writing and revising usually took up to a month.

LGBTQ+ representation

After the September 2011 episode "What Was Missing" hinted at romantic subtext between Marceline and Bubblegum, fans began to "ship" the two, referring to the pairing as "Bubbline". Some reviewers also discussed the possible relationship, with Kjerstin Johnson of Bitch magazine expressing hope that that show's "queer cartoon subtext" would turn into "a queer cartoon subplot". Eventually, Bubblegum and Marceline's relationship was confirmed in the series finale, "Come Along With Me", which also featured the two characters kissing. While Bubblegum seems to have dated a male character named Mr. Cream Puff, her exact sexuality, unlike Marceline's, has not been confirmed. As such, reviewers have argued that she is either bisexual, non-binary, queer, lesbian, or a combination of some of the latter, as both live in a world where "sexuality is somewhat fluid."

Much of the series' LGBTQ+ representation was the result of storyboard artist Rebecca Sugar, who soon after joining the production crew "became more aware of what we're really saying by excluding [LGBTQ] characters" from children's TV—a situation which felt "more and more dire" to her. She thus began working hard to put "LGBTQIA characters in G-rated content" in the years to follow. Zeroing in on the relationship between Marceline and Bubblegum, Sugar tried to foster their relationship. In a March 2021 Vanity Fair interview, Sugar said that she was encouraged by the "creative team to put their own life experiences into the character of Marceline," but when this led to a "romantic storyline between Marceline and Princess Bubblegum", Cartoon Network executives intervened. This moment led Sugar and the rest of the show's team to see the limit of what they could accomplish, in terms of representation. The writers initially responded to this roadblock by working queer themes into episodes as subtext to avoid controversy or network censorship, but later episodes would openly expand on these themes, bringing them to the forefront of the series' plot.

Finale

During the last seasons of Adventure Time, there was discussion at Cartoon Network about concluding the series. Olivia Olson, who provided the voice of Marceline, said that since this discussion wore on for a while, "the ending of the show was getting stretched and stretched and stretched". Chief content officer Rob Sorcher told the Los Angeles Times of the network's decision to end the series, saying:

Adventure Time was playing less and less on Cartoon Network, yet we were moving towards a large volume of episodes. And I really began thinking "[The end] can't come quickly as a sudden company decision, it needs to be a conversation over a period of time." And it did also strike me that if we don't wind this up soon, we're going to have a generation of fans graduate through the [television] demo [graphic that Cartoon Network targets] and we won't have completed a thought for them.

Consequently, on September 29, 2016, Cartoon Network confirmed that the series would conclude after its tenth season. The final episode of the series was a special, titled "Come Along with Me"; the special was written and storyboarded by Tom Herpich, Steve Wolfhard, Seo Kim, Somvilay Xayaphone, Hanna K. Nyström, Aleks Sennwald, Sam Alden, and Graham Falk. The story was developed by Herpich, Wolfhard, Ashly Burch, showrunner Adam Muto, head writer Kent Osborne, Jack Pendarvis, Julia Pott, and series creator Pendleton Ward. Former head background designer Ghostshrimp returned after having officially left the series during the fourth season.

According to Osborne, Cartoon Network provided the writers with "an opportunity to spend a lot of time thinking about the finale" before production ended. In an interview with TV Guide, Muto explained that the show's writers used many of the episodes preceding the finale to conclude minor character story arcs "so we wouldn't have to cram too much in at the very end here." This allowed the finale itself to be "less dense" by simply "hitting the big [beats] and then finding vignettes for all the characters ... so we could get snapshots of where they could end up." According to Pendarvis, storyline writing for the series ended in mid-November 2016, with the last storyline meeting held on November 21. A tweet by Osborne revealed that the series' final script was pitched to storyboarders, with Alden and Nyström in attendance, on November 28. This episode was then pitched to the show's producers during the third week of December 2016. Voice recording for the episode ended on January 31, 2017, as confirmed by a number of cast members, including Maria Bamford and Andy Milonakis. The series finale aired on September 3, 2018 to universal acclaim.

Broadcast and ratings

Episodes

Each Adventure Time episode is about eleven minutes in length; pairs of episodes are often telecast in order to fill a half-hour program time slot. Before the official debut of the first season, Cartoon Network aired both "Business Time" and "Evicted!" on March 11 and 18, respectively, advertising these showings as "previews" of the series-to-come. The show officially debuted with "Slumber Party Panic" on April 5, 2010.

During the latter part of its run, the show began to experiment with the miniseries format. The first of these was Stakes (2015), which aired during the show's seventh season. The following miniseries, Islands (2017) aired as part of the eighth season. The third and final miniseries, Elements (2017), aired during the show's ninth season.

The show's seventh season was originally intended to comprise 39 episodes, ranging from "Bonnie & Neddy" to "Reboot". However, when it came time to upload the season onto streaming sites like CartoonNetwork.com, Cartoon Network chose to end the season with the episode "The Thin Yellow Line", for a total of 26 episodes. This new episode count for the season was cemented by the release of the complete seventh season DVD on July 18, 2017, which included episodes "Bonnie & Neddy" through "The Thin Yellow Line". As such, the episode and season number sequence is accordingly changed, as follows:

For its first six seasons, episodes regularly aired once a week. Starting in November 2014, the show began to air new episodes via "bombs", or weeks in which new episodes debuted every day. This change in airing style disrupted the viewing patterns of some fans, as Dave Trumbore of Collider explained: "Back when [the show] was regularly airing in a more traditional schedule, it was a little easier to keep track of the completely insane episodes full of half-explained mythology and lots and lots of non-sequiturs. During the last few seasons, however, [when] the episodes started to arrive in more of a scattershot fashion scheduled around multi-part specials [it became easier to miss] the random airings of certain episodes".

The series' initial run concluded in 2018, after the airing of its tenth season. Reruns have aired on Boomerang and Adult Swim.

Ratings

Upon its debut, Adventure Time was a ratings success for Cartoon Network. In March 2013, it was reported that the show averaged roughly 2 to 3 million viewers an episode. According to a 2012 report by Nielsen, the show consistently ranked first in its time slot among boys aged 2–14. The show premiered on April 5, 2010, and was watched by 2.5 million viewers. The pilot episode was a ratings success. According to a press release by Cartoon Network, the episode's time slot saw triple-digit percentage increases from the previous year. The program was viewed by 1.661 million children aged 2–11, which marked a 110% increase from the previous year's figures. It was watched by 837,000 children aged 9–14, a 239% increase from the previous year's figures.

Between the second and sixth seasons, the show's ratings continued to grow; the second-season premiere was watched by 2.001 million viewers, the third-season premiere by 2.686 million, the fourth-season premiere by 2.655 million, the fifth-season premiere by 3.435 million, and the sixth-season premiere by 3.321 million. The show's seventh-season opener took a substantial ratings tumble, being watched by only 1.07 million viewers. Likewise, the eighth-, ninth-, and tenth-season premieres were watched by only 1.13, 0.71, and 0.77 million viewers, respectively. The series finale, "Come Along with Me", was viewed by 0.92 million viewers and scored a 0.25 Nielsen rating in the 18- to 49-year-old demographic, which means the episode was seen by 0.25 percent of all individuals aged 18 to 49 years old who were watching television at the time of the episode's airing.

Home media and streaming service

On September 27, 2011, Cartoon Network released the region 1 DVD My Two Favorite People, which features a selection of twelve episodes from the series' first two seasons. Following this, several other region-1 compilation DVDs have been released, including: It Came from the Nightosphere (2012), Jake vs. Me-Mow (2012), Fionna and Cake (2013), Jake the Dad (2013), The Suitor (2014), Princess Day (2014), Adventure Time and Friends (2014), Finn the Human (2014), Frost & Fire (2015), The Enchiridion (2015), Stakes (2016), Card Wars (2016), and Islands (2017). All of the seasons have been released on DVD, and the first six have been released domestically on Blu-ray. A box set containing the entire series was released on DVD on April 30, 2019.

On March 30, 2013, the first season of Adventure Time was made available on the Netflix Instant Watch service for online streaming; the second season was made available on March 30, 2014. Both seasons were removed from Netflix on March 30, 2015. The series was made available for streaming via Hulu on May 1, 2015.

While in the United States, HBO Max becomes the primary platform to watch Adventure Time: Distant Lands, there are debuts of "BMO", the first special of the spin-off series, in different countries and regions in respective Cartoon Network channels worldwide, on different dates mainly in 2020; such as October 24 (Turkey), October 25 (France), November 21 (the United Kingdom), December 12 (Germany, Australia, and Taiwan), and December 27 (Russia). In South Korea, the debut was on January 1, 2021.

Reception

Critical reception

Adventure Time received widespread critical acclaim. The A.V. Club reviewer Zack Handlen called it "a terrific show [that] fits beautifully in that gray area between kid and adult entertainment in a way that manages to satisfy both a desire for sophisticated (i.e., weird) writing and plain old silliness".

The show has been praised for its resemblance to cartoons of the past. In an article for the Los Angeles Times, television critic Robert Lloyd compared the series to "the sort of cartoons they made when cartoons themselves were young and delighted in bringing all things to rubbery life". Robert Mclaughlin of Den of Geek expressed a similar sentiment when he wrote that Adventure Time "is the first cartoon in a long time that is pure imagination". He complimented the show for "its non-reliance on continually referencing pop culture". Eric Kohn of IndieWire said the show "represents the progress of [cartoon] medium" in the current decade.

A number of reviews have positively compared the series and its creators to other culturally significant works and individuals, respectively. In 2013, Entertainment Weekly reviewer Darren Franich called the series "a hybrid sci-fi/fantasy/horror/musical/fairy tale, with echoes of Calvin and Hobbes, Hayao Miyazaki, Final Fantasy, Richard Linklater, Where the Wild Things Are, and the music video you made with your high school garage band". Emily Nussbaum of The New Yorker praised Adventure Time's unique approach to emotion, humor, and philosophy by likening it to "World of Warcraft as recapped by Carl Jung". Zack Handlen of The A.V. Club concluded that the show was "basically what would happen if you asked a bunch of 12-year-olds to make a cartoon, only it's the best possible version of that, like if all the 12-year-olds were super geniuses and some of them were Stan Lee and Jack Kirby and the Marx Brothers".

Adventure Time's willingness to explore dark, depressing, and complex issues has received praise. Kohn applauded the fact that the show "toys with an incredibly sad subtext". Novelist Lev Grossman, in an interview with NPR, praised the backstory of the Ice King and the exploration of his condition in the third-season episode "Holly Jolly Secrets", the fourth-season episode "I Remember You", and the fifth-season episode "Simon & Marcy", noting that his origin is "psychologically plausible". Grossman praised the way the series was able to tackle issues of mental illness, saying: "It's very affecting. My dad has been going through having Alzheimer's, and he's forgotten so much about who he used to be. And I look at him and think this cartoon is about my father dying". Critics have suggested that the show has grown and matured as it has aged. In a review of season four, for instance, Mike LeChevallier of Slant magazine complimented the show for "growing up" with its characters. He concluded that the series has "strikingly few faults" and awarded the fourth season three-and-a-half stars out of four.

Industry impact

Several former crew members who worked on Adventure Time have gone on to create their own series, including Patrick McHale (a former storyline writer, storyboard artist, and creative director who went on to create Over the Garden Wall), J.G. Quintel (a former storyboard artist who went on to create Regular Show and Close Enough), Pete Browngardt (a former storyboard artist who went on to create Secret Mountain Fort Awesome, Uncle Grandpa, and Looney Tunes Cartoons), Rebecca Sugar (a former storyboard artist who went on to create Steven Universe), Ian Jones-Quartey (a former storyboard revisionist and supervisor who went on to create OK K.O.! Let's Be Heroes), Skyler Page (a former storyboard artist who went on to create Clarence), Julia Pott (a former storyline writer who went on to create Summer Camp Island), Kent Osborne (the show's former head story writer who went on to create Cat Agent), and Elizabeth Ito (a former storyboard artist and supervising director who created City of Ghosts for Netflix).

Heidi MacDonald of Slate argued that the scouting of indie comic creators employed by Adventure Time (as well as several other Cartoon Network and Nickelodeon series) has led to an "animation gold rush" in which major studios are actively seeking under-the-radar talent for their shows, with her article surmising that "your favorite brilliant indie cartoonist is probably storyboarding for Adventure Time". MacDonald also pointed out that Adventure Time has influenced the tone of modern comics, noting:

If anything, walking around [comic] shows like SPX, I've noticed something of an Adventure Time track among many of the small press comics now coming out: Where once young cartoonists overwhelmingly produced gloomy masculine self-absorption and misanthropy in the tradition of Daniel Clowes or Chris Ware, these days many booths feature fantasy epics with colorful characters and invented worlds heavy on the talking animals. It shouldn't be surprising that up-and-coming cartoonists are absorbing the Adventure Time aesthetic. A 20-year-old making comics now could have been watching the show since she was 15, after all.

In an interview with Paste magazine, Sugar explained that working on Adventure Time and connecting with indie and underground comic artists who worked on the show (like Ward, McHale and Muto) was a creative game-changer, as they told her to do what she would do when drawing comics and to not hold anything back. She argued that many of the recent developments in animation were inspired by what the show was able to do by being "very artist-driven" and allowing independent comic artists to have a major say in the direction of episodes.

Academic interest

Adventure Time has attracted academic interest for its presentation of gender and gender roles. Emma A. Jane, an academic from the University of New South Wales in Sydney, Australia, wrote that while the two main characters are male and many episodes involve them engaging in violent acts to save princesses, "Finn and Jake are [nevertheless] part of an expansive ensemble cast of characters who are anything but stereotypical and who populate a program which subverts many traditional gender-related paradigms". She said the show features "roughly equal numbers of female and male characters in a protagonist, antagonist, and minor roles"; includes characters with no fixed gender; uses "gendered 'design elements'" such as eyelashes and hair to illustrate character traits rather than gender; equally distributes traits regardless of gender; privileges found, adoptive families or extended families; frames gender in ways that suggest it is fluid, and features elements of queer and transgender subtext. Carolyn Leslie, writing in Screen, agrees, saying, "despite having two male leads, Adventure Time is particularly strong when it comes to questioning and challenging gender stereotypes". She cited Princess Bubblegum, BMO, and Fionna and Cake as examples of characters who refuse to be readily categorized and genderized.

The first non-fiction book to scholarly study the series was Adventure Time and Philosophy (2015), edited by Nicolas Michaud. Published by Open Court Publishing Company, this work considers Adventure Time from a variety of angles, using the show as a way to explore different philosophical angles and ideas. In July 2020, independent scholar Paul A. Thomas released a book entitled Exploring the Land of Ooo that documented the show's production history; an expanded and updated version of the book was released in 2023 by the University Press of Mississippi.

Fandom

Since its debut, Adventure Time has developed a strong following among children, teenagers, and adults; according to A.V. Club critic Noel Murray, fans are drawn to Adventure Time because of "the show's silly humor, imaginative stories, and richly populated world". While the show is often described as having a cult following, Eric Kohn of IndieWire said that the series has "started to look like one of the biggest television phenomenons of the decade". According to Alex Heigl of People magazine, "The show's fandom is especially Internet-savvy as well, with huge communities on Reddit, Imgur and Tumblr, who swap GIFs, fan art and theories with fervent regularity". In 2016, a study by The New York Times of the 50 TV shows with the most Facebook Likes found that Adventure Time "is the most popular show among the young in our data—just over two-thirds of 'likes' come from viewers [aged] 18–24".

The show is a popular presence at fan conventions, such as San Diego Comic-Con. Reporter Emma-Lee Moss said, "This year's [2014] Comic-Con schedule reflected Adventure Time's growing success, with several screenings [as well as] a dramatic reading with the show's voice talent". The show is also popular with cosplayers, who are performance artists that wear costumes and fashion accessories to represent characters from any given series. Moss wrote, "Looking into the crowd, it was clear that [Finn's] distinctive blue shirt and white hat were being mirrored by hundreds of Cosplayers, male and female". In an interview, Olivia Olson (who voices the character Marceline) said, "Literally, anywhere you look, anywhere in your range, you're going to see at least two people dressed up like Finn. It's crazy".

Video games

The series has spawned several major video game releases. The first game based on the series, Adventure Time: Hey Ice King! Why'd You Steal Our Garbage?!!, was announced by Pendleton Ward on his Twitter account in March 2012. The game was developed by WayForward Technologies for Nintendo DS and Nintendo 3DS, and was released by D3 Publisher on November 20, 2012. A year later, the game Adventure Time: Explore the Dungeon Because I Don't Know!, which follows Finn and Jake as they strive "to save the Candy Kingdom by exploring the mysterious Secret Royal Dungeon deep below the Land of Ooo", was released in November 2013. On November 18, 2014, Adventure Time: The Secret of the Nameless Kingdom was released for Nintendo 3DS, Xbox 360, PlayStation 3, PlayStation Vita, and Microsoft Windows. In October 2015, the fourth major Adventure Time video game, titled Finn & Jake Investigations, was released for 3DS, Windows and other consoles. It is the first in the series to feature full 3D graphics. Another game, Adventure Time: Pirates of the Enchiridion, was released for the PlayStation 4, Nintendo Switch, Windows, and Xbox One in July 2018. The game was published by Outright Games, developed by Climax Studios, and features the show's original cast. That game won the award for "Performance in a Comedy, Lead" with John DiMaggio at the National Academy of Video Game Trade Reviewers Awards, in which Jeremy Shada was also nominated for the same category.

Various other minor video games have also been released. Several, including Legends of Ooo, Fionna Fights, Beemo – Adventure Time, and Ski Safari: Adventure Time, have been released on the iOS App Store. A game titled Finn & Jake's Quest was released on April 11, 2014, on Steam. Cartoon Network also released a multiplayer online battle arena (MOBA) game titled Adventure Time: Battle Party on Cartoon Network's official site, on June 23, 2014. In April 2015, two downloadable content packs for LittleBigPlanet 3 on PlayStation 3 and PlayStation 4 were released; one contained Adventure Time costumes, while the other contained a level kit with decorations, stickers, music, objects, a background, and a bonus Fionna costume. A virtual reality (VR) game entitled Adventure Time: Magic Man's Head Games was also released to Oculus Rift, HTC Vive, and PlayStation VR. A second VR game, entitled Adventure Time: I See Ooo, was released on September 29, 2016. In that same month, Adventure Time characters were added to the Lego Dimensions game. Finn and Jake became playable characters in the video game Cartoon Network: Battle Crashers which was released for the Nintendo 3DS, PlayStation 4, Xbox One on November 8, 2016 and the Nintendo Switch on October 31, 2017. Finn, Jake, Banana Guard, and Marceline are playable characters in the platform fighter MultiVersus.

Film

In February 2015, it was reported that a theatrical Adventure Time film was being developed by Cartoon Network Studios, Frederator Films, Vertigo Entertainment, and Warner Animation Group. According to reports, the film would be executive-produced and written by Pendleton Ward, and produced by Roy Lee and Chris McKay. In October 2015, series producer Adam Muto confirmed that series creator Pendleton Ward was "working on the premise" for the film, but that there was "nothing official to announce yet". On July 22, 2018, Muto noted that "an [Adventure Time] movie was never officially announced". On August 31, 2018, Muto said the finale of the show would not affect a potential movie, nor would the finale lead directly into a film. He also noted that "all the lore and stuff would not work for a first time viewer", suggesting that the film would have to hold well on its own to be successful.

However, on June 12, 2024, during the Annecy Animation Festival, it was announced that an Adventure Time movie was in development, with Rebecca Sugar, Adam Muto, and Patrick McHale all involved in the project.

Other appearances

A variety of officially licensed merchandise—including action figures, role-playing toys, bedding, dishware, and various other products—have been released. Since the dramatic increase in popularity of the series, many graphic T-shirts have been officially licensed through popular clothing retailers. Pendleton Ward hosted T-shirt designing contests on the websites of both We Love Fine and Threadless. Other shirts can be purchased directly from Cartoon Network's store. A collectible card game called Card Wars, inspired by the fourth-season episode of the same name, has been released. On March 11, 2016, it was announced by Lego via Lego Ideas that an official Adventure Time Lego set from an idea by site user, aBetterMonkey, had met voting qualifications and was approved to be produced in cooperation with Cartoon Network. The set was released in January 2017.

On July 21, 2013, Taiwan High Speed Rail and the Taiwan branch of Cartoon Network worked together on a project called "Cartoon Express" (歡樂卡通列車). The entire train was covered with characters from various Cartoon Network shows (including The Amazing World of Gumball, The Powerpuff Girls, Ben 10, and Regular Show), and the two sides of the train is painted with Finn and Jake respectively. Throughout the project, there were over 1,400 runs of the train and over 1.3 million passengers were transported. Near the end, the Taiwan High Speed Rail also sold postcards as souvenirs for sale since August 23, 2014, and the project eventually ended on September 9, 2014. In addition, Cartoon Network established a waterpark named Cartoon Network Amazone in Chonburi, Thailand; it opened on October 3, 2014. Promoting the waterpark, Thai Smile painted Finn, Jake, Princess Bubblegum and Marceline on the planes.

"Leela and the Genestalk", an episode from the seventh season of the animated Comedy Central program Futurama, features a cameo of Finn and Jake, with DiMaggio (who voices Bender in Futurama) reprising his role as Jake for the appearance. Similarly, the twenty-eighth season premiere of the Fox series The Simpsons, entitled "Monty Burns' Fleeing Circus", includes a couch gag that parodies the title sequence to Adventure Time, complete with Pendleton Ward himself singing a spoof of the Adventure Time theme song. According to Al Jean, the executive producer of The Simpsons, "[The couch gag] was the brain child of Mike Anderson, our supervising director ... It's a really beautiful, elaborate crossover".

On the Portuguese talk show 5 Para A Meia-Noite, the humorist Eduardo Madeira, who portrayed a hater called Osório, used Princess Bubblegum and Marceline to mock the Eurovision Song Contest 2018's Portuguese contestants, Cláudia Pascoal and Isaura.
