The Big Sleep (1946)
Howard Hawks' 1946 Chandler adaptation. Plot incomprehensible even to the screenwriters.
Writer: William Faulkner
William Faulkner co-wrote To Have and Have Not and The Big Sleep for Howard Hawks and won the Nobel Prize in Literature for the novels. He took screenwriting work purely for money, drank heavily through it, and reportedly asked whether he could work from home, meaning Mississippi.
