Terrence Vance Gilliam is an American-British filmmaker, comedian, collage animator and actor. He gained stardom as a member of the Monty Python comedy troupe alongside John Cleese, Eric Idle, Michael Palin, Terry Jones, and Graham Chapman. Together they collaborated on the sketch series Monty Python's Flying Circus (1969–1974) and the films Monty Python and the Holy Grail (1975, which Gilliam co-directed as well), Life of Brian (1979) and The Meaning of Life (1983). In 1988, they received the BAFTA Award for Outstanding British Contribution to Cinema. In 2009, Gilliam received the BAFTA Fellowship for lifetime achievement.
Gilliam transitioned to directing serious films with themes exploring imagination and oppositions to bureaucracy and authoritarianism. His films are sometimes set in dystopian worlds and involve black comedy and tragicomedic elements. He has directed 13 feature films, gaining acclaim for Time Bandits (1981), Brazil (1985), The Adventures of Baron Munchausen (1988), The Fisher King (1991), 12 Monkeys (1995), and Fear and Loathing in Las Vegas (1998). He later directed The Brothers Grimm (2005), Tideland (2005), The Imaginarium of Doctor Parnassus (2009), The Zero Theorem (2013), and The Man Who Killed Don Quixote (2018).
Gilliam was born in Minnesota, but spent his high school and college years in Los Angeles. He started his career as an animator and strip cartoonist. He joined Monty Python as the animator of their works, but eventually became a full member and was given acting roles. The only Monty Python member not born in Britain, Gilliam became a naturalised British citizen in 1968 and formally renounced his American citizenship in 2006.
