Catch-22 is a 1970 American satirical black comedy war film adapted from the 1961 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 worked on the film script for two years, converting Heller's complex novel to the medium of film.

Catch-22 is a satirical war novel by American author Joseph Heller. He began writing it in 1953; the novel was first published in 1961. Often cited as one of the most significant novels of the twentieth century, it uses a distinctive non-chronological third-person omniscient narration, describing events from the points of view of different characters. The separate storylines are out of sequence so the timeline develops along with the plot.
