Catch-22 is a 1970 American black comedy war film adapted from the novel of the same name by Joseph Heller. In creating a black comedy revolving around the “lunatic characters” of Heller’s satirical anti-war novel set at a fictional Mediterranean base during World War II, director Mike Nichols and screenwriter Buck Henry (also in the cast) worked on the film script for two years, converting Heller’s complex novel to the medium of film.
