Query: Murder on the Orient Express

An unrecognizable Finney transforms himself into Agatha Christie's renowned Belgian sleuth, Hercule Poirot. Beyond this star's astonishing portrayal, the fun of this whodunit comes from the fascinating assortment of characters he interrogates, played by some of our most accomplished acting veterans: Lauren Bacall, Ingrid Bergman, Sean Connery, Wendy Hiller, and John Gielgud among them. Predictably, in addition to Finney, old pros Hiller and Gielgud steal the show. "Murder" should be nirvana for any mystery lover, and director Lumet gives the film plenty of period charm and atmosphere.
