Next time you’re in the shower, make sure Norman Bates or his mother are nowhere to be found. Ranked number one by the American Film Institute’s 100 Years, 100 Thrills, this Alfred Hitchcock movie still stands, even after 40 years, as one of the most scary, if not scariest films of all time. Psycho is not a horror film—it is just a fast-paced thriller that thrills a little more than most Hitchcock films. Also contributing to the “horror” quality are a very memorable ending and one of the most copied, talked-about, and studied film scenes ever…the shower scene. Hitchcock took quite a few chances when making Psycho. First, his leading lady Janet Leigh is out-of-the-picture about a third into the film. Then, the director chose to shoot the film in black and white, something that was not done that often in 1960. Hitchcock also cast lesser-known actors to play other key role, especially then-unknown Anthony Perkins as Norman Bates. Those risks paid off and placed Psycho at the top of Hitchcock’s best films.
