The Big Sleep is a 1946 American film noir directed by Howard Hawks, the first film version of the 1939 novel of the same name by Raymond Chandler. The film stars Humphrey Bogart as private detective Philip Marlowe and Lauren Bacall as Vivian Rutledge in a story about the "process of a criminal investigation, not its results". William Faulkner, Leigh Brackett and Jules Furthman co-wrote the screenplay. In 1997, the U.S. Library of Congress deemed the film "culturally, historically, or aesthetically significant," and added it to the National Film Registry.
