1978 Remake
A remake starring Robert Mitchum as Philip Marlowe was released in 1978. This was the second movie in three years featuring Mitchum as Marlowe. Many have noted that while it was more faithful to the novel, due to lack of restrictions on what could be portrayed on screen, it was far less successful than the original 1946 version with Bogart and Bacall.
