Sidney Lumet managed with "Murder on the Orient Express" to do something no other director of film based on a Christie novel had done. He pleased Dame Agatha. No easy feat, but possible because of the brilliant cast. My personal feeling is that Albert Finney overacted Poirot, and was the wrong body type, from Christie's descriptions in her books, despite which he was believable. Ingrid Bergman deserved her Academy Award win for Best Supporting Actress in this film. Every performance in this feature was carefully and skillfully crafted, as well crafted as the beautiful sets of the train, recreated from only partial portions of the original cars. This is the kind of detailed movie that works without special effects and with very flavorful script writing. Not to be missed.
