Intertextuality

Intertextuality is when films 'borrow' ideas from each other ie- when films take aspects from another film and use it in their own. They usually be using visual references from famous influential films, for example the Psycho. The shower scene is very famous and other films seem to borrow it. films such as 'What Lies Beneath' 'Fatal Attraction' and 'The Stepfather' This is because they uses a lot of the same elements from that scene, which showed the intertextuality. All these films use a female victim who is in danger from a similar knife. The scenes include a shower curtain, the bath a bath robe worn by the characters in each clip; they all use violin to give the thriller effect.
