Early life
Walton was born Mark Daniel Walton in Salt Lake City, Utah, on October 24, 1968, the oldest of seven children.
Although not a professional actor, Walton said in an interview, "I liked acting in high school and college. I enjoyed it. I think at some point, I decided that if I was really going to be a professional actor that it would take at least everything that I would have emotionally or physically and I knew that I really wanted to
pursue art."
In 1998, he graduated from Utah State University with a degree in illustration.
Career
In 1995, Walton started at Walt Disney Feature Animation Florida as a story and animation intern. After performing as a show artist for The Hunchback of Notre Dame Musical Discovery Adventure North American Mall Tour in 1996, he transferred to Walt Disney Feature Animation in Burbank, California (now known as Walt Disney Animation Studios) in 1997 to work on his first feature Tarzan as a storyboard artist. While at Disney, from the late 1990s and throughout the 2000s, he did storyboards for The Emperor's New Groove, The Little Matchstick Girl, Home on the Range, Chicken Little, Meet the Robinsons, Tangled, and Gnomeo and Juliet, as well as storyboarding and developing the unproduced films Wild Life, My Peoples, and Rapunzel Unbraided (an early version of Tangled), Joe Jump, and King of the Elves. Also, while at Disney, he provided the voices for Barry & Bob the Longhorns in Home on the Range (2004), Goosey Loosey for Chicken Little and its video game (2005), and for Rhino the hamster in Bolt (2008) for which he was nominated for an Annie Award for Voice Acting in a Feature Production, and the short film spin-off Super Rhino.

Numerous positive reviews came from film critics regarding Walton's performance as Rhino in Bolt. CNN noted “Walton's Rhino steals every scene he's in.”, while Enewsi stated "Walton has perfect comedic timing as Rhino". Another reviewer noted “The hamster alone is enough to make this movie worth seeing”, with other positive reviews featured in the New York Times and the Los Angeles Times, where Walton contemplated Rhino's popularity as, "he imagines he's actually something bigger and more powerful to match his big heart and big dreams -- which can't be contained by his little hamster body."
Personal life
Walton was raised in Salt Lake City, Utah, where he grew up alongside six younger siblings. He spent 18 years living and working in Southern California to pursue his Hollywood animation career before deciding to relocate back to his hometown.
Walton resides in a historic home in the Avenues neighborhood of Salt Lake City, located one block away from his childhood home and directly across the street from the elementary school he attended as a child. The home originally belonged to longtime family friends before Walton's own children later came to occupy the same space.
