I took The Big Sleep to The Grandmother's house to watch. I had seen it several times before, but she had never seen it. This 1946 film is based on a book by the same name by Raymond Chandler. It is directed by Howard Hawks and stars Humphrey Bogart and Lauren Bacall. Also in this movie are Dorothy Malone, Elisha Cook, Jr. and Ben Weldon.
Images Journal has a review, as do Reel Classics, Senses of Cinema, the New York Times and Salon.com. Roger Ebert considers it a "Great Movie".
