Curiosidades

Due to Humphrey Bogart's affair with co-star Lauren Bacall, his marital problems escalated during filming, and his drinking often resulted in his being unable to work. Three months after the film was finished, Bacall and Bogart were married.

Raymond Chandler claimed that Martha Vickers gave such an intense performance as Carmen Sternwood that she completely overshadowed Lauren Bacall, and that much of Vickers' performance ended up on the cutting room floor as a result.

In re-cutting the film, Howard Hawks removed the scene in which Marlowe explains the crimes. The film's success supported his growing conviction that audiences didn't care if a plot made sense as long as they had a good time.

According to Lauren Bacall, production was such fun that they got a memo from Jack L. Warner saying, "Word has reached me that you are having fun on the set. This must stop."

Warner Bros. studio chief Jack L. Warner gave Howard Hawks $50,000 to purchase the rights for the source novel. Hawks bought the rights for $5,000 and pocketed the rest. According to film historian Jon Tuska, the purchase price was actually $10,000.
