Terry Gilliam was born on 22nd November 1940 and gained his reputation as an auteur by starting his career as an animator and strip cartoonist, and was an animator for monty python, later appearing in occasional scenes as an actor for the group. Gilliam became a screen-writer and director after the gradual split up of his previous group in monty python. His first film was called "Time Bandits" appearing in 1981, and wrote two other movies, "Brazil" and "The adventures of Baron Munchausen", in a trilogy of movies depicting the "craziness of our awkwardly ordered society and the desire to escape it through whatever means possible."
