MURDER ON THE ORIENT EXPRESS (1974)

This tour-de-force treatment of a juicy Agatha Christie mystery, directed by the great Sidney Lumet, features an all-star cast of seemingly unrelated, unconnected conspirators who kill a tough gangster (Richard Widmark) on the famous European luxury train. It's eventually unraveled by Christie's inimitable Belgian detective Hercule Poirot (Albert Finney in a world-beating performance). There's plenty of dry humor mixed in with the murderous hi-jinks, much of it supplied dead-pan by Finney. Filming is luxurious, but it's a bit slow going, particularly at the end.
