1. American Psycho (2000): The 2000 movie "American Psycho" directed by Mary Harron incorporates elements of the Psycho score throughout the film. The iconic shower scene in "American Psycho" is accompanied by a modern techno remix of Herrmann's original Psycho music, creating an eerie and unsettling atmosphere.
2. The Simpsons Treehouse of Horror Episode "Dial Z for Zombies" (1994): This episode includes a segment where Bart becomes a zombie and chases his family around the house. During this scene, a variation of the Psycho shower music can be heard, paying homage to the classic horror film.
3. Fargo (1996): The Coen Brothers' film "Fargo" features some subtle nods to the Psycho score. For instance, the scene where Marge Gunderson (Frances McDormand) steps into the snowy field to examine the body of the victim bears a resemblance to Marion Crane's murder scene from Psycho, and it is accompanied by eerie music that evokes Herrmann's original composition.
4. Cabin in the Woods (2012): This horror-comedy film makes several references to classic horror movies, including Psycho. At one point, the character Marty (Fran Kranz) is trapped in a bathroom and becomes increasingly panicked as the music starts to swell, mirroring Marion Crane's experience in the shower scene from Psycho.
These are just a few examples of how the iconic musical score from Psycho has been referenced and used in other films as a way to pay tribute to the original masterpiece and create a specific mood or atmosphere within their own narratives.
