Murder, My Sweet

Lots of actors have played Raymond Chandler's world-weary protagonist Philip Marlowe. You'd expect my favourite would be Humphrey Bogart, but the best one for my money was Dick Powell in this 1944 adaption of Farewell, My Lovely, which is also one of the best Chandler books:

Marlowe is hired by "Moose" Malloy (played to perfection by Mike Mazurki) to find his old girlfriend Velma. It's full of great one-liners:

"She could take a drink. She had to knock it down to get to the bottle."

Helen Grayle: "I'm just going to powder my nose"
Marlowe: "It's already got powder on it"
