Directed by Alfred Hitchcock and starring Farley Granger and Robert Walker. Neither of these actors became big stars in their own right, but Hitchcock was oblivious to big actors, anyway, since he considered all actors as merely props in his films. The real star of the movie is the script, which is dripping with suspense and will keep you engaged from beginning to end. The story revolves around a tennis star, Guy (Granger) who is travelling by train and casually mentions to a passenger, Bruno (Walker) that he is not really in love with his current wife and would love to get rid of her. Bruno concocts a scheme about how one can commit the perfect murder if the suspect has no motive. He wants his father killed and offers to kill Guy’s wife in exchange for Guy killing Bruno’s father. Neither man would then have a motive. Guy leaves thinking the plan insane, but Bruno considers his silence as consent and commits the first murder. He is in possession of Guy’s lighter (that’s what happens when you smoke) and plans to plant it at the murder scene if Guy backs out; which he does. I will not reveal the ending of the movie, but I can highly recommend it as one of Hitchcock’s best films. This film is in both my and many other top 100 film lists.
