Biography

Henry Cornelius Garrett, of English, Dutch, and Irish descent, was born into a theatrical family in Bristol, UK. The son of a costume designer and an actor, his early focus was on athletics, a pursuit that took him to the United States.

Whilst studying Media and Journalism in New York City - aiming for a career in documentary filmmaking - he lived above a downtown theatre. One evening he snuck into Simon McBurney’s production of The Resistible Rise of Arturo Ui, starring Al Pacino with a cast including Billy Crudup, Chazz Palminteri, Paul Giamatti, John Goodman, and Steve Buscemi.

Inspired, he immediately began taking acting classes and performing in plays such as John Patrick Shanley’s Danny and the Deep Blue Sea, before formalizing his training at The Lee Strasberg Theatre Institute under mentors like Paul Calderon, Pennie DuPont, and George Loros.

Garrett's film work includes Ivan Kavanagh’s award-winning improvised drama The Fading Light (2009), A Little Chaos (2014) directed by and starring Alan Rickman, Testament of Youth (2014) opposite Alicia Vikander, and Ron Howard’s true-life drama Alone at Dawn (2026) with Adam Driver.

On television he has appeared in the BAFTA-winning series Skins (2009) and Poldark (2015), acclaimed drama Peaky Blinders (2013), Michael Winterbottom’s limited series This England (2022) for Sky and Graham Yost’s sci-fi epic Silo (2023).
