The Spook Who Sat by the Door a 1973 film, which is based on the novel The Spook Who Sat By The Door by Sam Greenlee. It is both a satire of the civil rights struggle in the United States of the late 1960s and a serious attempt to focus on the issue of black militancy. Dan Freeman, the titular protagonist, is enlisted in the Central Intelligence Agency's elitist espionage program as its token black. Upon mastering agency tactics, however, he drops out to train young Chicago blacks as "Freedom Fighters." As a story of one man's reaction to ruling-class hypocrisy, the film is loosely autobiographical and personal.

The novel and the film also dramatize the CIA's history of giving training to persons and/or groups who later utilize their specialized intelligence training against the agency
