Early life and education
Harrison Cosmo Krikoryan-Jarvis was born in 1989 or 1990 in New Jersey, U.S., to an Armenian-American mother and British father. His grandparents were Armenian immigrants. He moved to Britain with his parents at the age of three months, and moved to Totnes, Devon, as a child, with his mother and younger brother. About his nationality, Jarvis has said: "I came here [Britain] when I was a baby. I've never lived [in America] ... I don't feel a connection to anywhere."
Music career
Jarvis confirmed his second album's title as Is the World Strange or Am I Strange? on his official Facebook page. The first single released from the album was "Gay Pirates", which was released on 23 January 2011. The single's music video was directed by Jarvis. The song was featured as Record of the Day and AOL's Spinner video of the day. "Gay Pirates" was voted number 85 on the Triple J Hottest 100 of 2011, which aired on Australia Day in 2012. The album itself was given an 8.5/10 rating from Soundblab album reviews. He announced in an interview with TNC that he had begun work on his first feature film, called The Naughty Room.
The film premiered on BBC Four on 20 August 2012, shortly after the release of Jarvis' third studio album, titled Think Bigger, the film includes multiple songs/variations of songs from the album in the soundtrack. He toured the UK in late 2012 supporting Mad Dog Mcrea, for whom he penned the song "Waiting on the Hill". The comedy film Hawk(e): The Movie (2013) features several songs by Jarvis. In January 2013, "Love This" came in at number 59 on the Triple J Hottest 100, 2012. On 20 November 2020, Jarvis re-released his 2012 album Think Bigger as Think Bigger - (2020 Deluxe Edition), as the 2012 album was never fully released globally. The Think Bigger reissue contains all of its 11 original recordings remastered for 2020, plus a further nine bonus tracks from that same writing period, including five never before heard songs and four acoustic live 'bedroom' versions of key Think Bigger tracks.
Jarvis confirmed in 2025 that he is no longer active as a musician.

In 2015, Jarvis auditioned and was cast to portray the character of Sebastian in William Oldroyd's debut feature film Lady Macbeth. Jarvis has starred in two stage plays directed by Richard Jones, the 2017 production of The Hairy Ape by Eugene O'Neill at Park Avenue Armory in New York and The Twilight Zone at the Almeida Theatre in London.
In 2019, his portrayal of Arm in the independent film Calm with Horses earned him a nomination as Best Actor at the British Independent Film Awards 2020 and London Film Critics' Circle. Adapted from the short story of the same name from the collection Young Skins by Colin Barrett, Calm with Horses was received positively, with critics praising both Nick Rowland's work as a debut director and Jarvis' performance as Douglas Armstrong. The film was released in the United States under the title The Shadow of Violence. In 2020, Jarvis was a guest star on the fifth season of Peaky Blinders, as the character Barney. Following Peaky Blinders, Jarvis appeared in Nocturnal, Funny Face, The Evening Hour and Raised by Wolves.
In 2021, Jarvis was announced to star opposite Dakota Johnson in Netflix's adaptation of Jane Austen's Persuasion. He was also cast as John Blackthorne, a leading role opposite Hiroyuki Sanada in FX's 2024 limited-series Shōgun, the second TV adaptation of James Clavell's best-selling novel of the same name. In 2022, Jarvis was nominated for Best Lead Performance in the British Independent Film Awards' new gender-neutral category for his performance in It Is In Us All. He was also nominated for Best International Actor at the Irish Film and Television Awards.
FX's Shōgun premiered in February 2024, receiving critical acclaim worldwide. Jarvis' performance as John Blackthorne was described as a "force to be reckoned with" by IGN and The Washington Post wrote that he "brilliantly channels" his role as the marooned English pilot in the historical drama. Empire described Jarvis as "compelling" and "magnetic". In his review, Nick Clark wrote for the Evening Standard, "Jarvis is one of those actors who is not just chameleonic – anyone who has seen him in Calm with Horses and then Persuasion can attest to his powers of transformation – but always brings so much more to a role than just speaking the words in order. It's the eyes; there's a whole lot going on behind them, and it means he's never less than compelling."

Views
Jarvis has stated an aversion to social media and contemporary U.K. politics.
In an interview with Crush Fanzine in 2021, Jarvis spoke about recognition of the Armenian genocide: “I do find it fascinating that the Armenian genocide… is still not acknowledged by some nations… certain genocides and tragedies can be openly minimized or discounted all together while others happen to become essential architecture of a pop culture and society.”
