Which 1941 film introduced Humphrey Bogart as private detective Sam Spade?

The 1941 film that introduced Humphrey Bogart as private detective Sam Spade was The Maltese Falcon. John Huston directed the film and adapted it from Dashiell Hammett’s 1930 novel.

Bogart’s Sam Spade is a San Francisco private investigator drawn into a search for a valuable statuette. The film also stars Mary Astor, Peter Lorre, and Sydney Greenstreet. Its plot revolves around shifting alliances, deception, and competing attempts to obtain the falcon.

The film is widely regarded as a landmark of film noir. Its sharp dialogue, morally uncertain characters, urban interiors, and compressed investigation became models for later crime movies. Huston’s screenplay retained much of Hammett’s story while translating the novel’s hard-boiled style to the screen.

The Maltese Falcon is sometimes confused with The Big Sleep, another celebrated Bogart detective film. In The Big Sleep, Bogart plays Philip Marlowe, Raymond Chandler’s detective, not Sam Spade.
