'The Big Sleep', based on the Raymond Chandler novel of the same name is one of the all-time great Hollywood films. Directed by Howard Hawks, with a screenplay written by William Faulkner, a Nobel prize winning author, and starring Humphrey Bogart and Lauren Bacall the film features murder, gambling, blackmail, intrigue and love. The film follows the progress of private eye Philip Marlowe (Humphrey Bogart) as he investigates the shady goings on of two girls on behalf of their father. The plot is so convoluted that famously even Raymond Chandler himself was unsure of whether one of the characters was murdered or committed suicide. Much of the continued success of The Big Sleep revolves around its great dialog and the on-screen chemistry between Bacall and Bogart but for whatever reason this is certainly a film to see.
