This is a masterpiece by the Master of Suspense, Alfred Hitchcock. It can be best described as a psychological thriller. It was made in 1950. The film has a strong cast of Farley Granger and Robert Walker, supported by Ruth Roman. The narration is based on Patricia Highsmith's novel.
Some of the highlights of the film that you simply cannot erase from your memory are the strangling scene in an amusement park that is shot from an isolated right frame of a fallen pair of spectacles. It is simply spectacular and unique way of filming. Another unforgettable scene where Walker crashes the Senator's party and tries to demonstrate how easy it is to choke a victim. His relationship with his parents is brought out admirably by Hitchcock. The finale at the merry go round is a cracker of a scene. The film's narrative is built around the events on a train as a binding link; another link that binds the tale is Granger's cigarette lighter which he receives as a gift from Roman.
