Intertextuality is a term to describe the visual referencing between films. Quite literally, films 'borrow from each other, and you may recognise certain camera angles, aspects of mise en scene, snippets of sound or methods of editing in some films that you have seen in other.
What interests me about 'Intertextuality' is how many film companies use the same settings, sounds and even camera work as other films. By doing this it gives the audience an advantage of knowing what's going to happen to the victim. Examples of films that do this are, 'What lies beneath', 'Fatal Attraction', 'The Stepfather' and 'Sccubus', all of these films 'borrow' ideas from the famous shower in Psycho. These more modern films use the same mise en scene of a bathroom with white tiles, a white shower curtain and a white bath tub. They also use some of the camera angles used in Psycho like the birds eye view of the shower head. Many suspenseful films decide to use a bathroom for a murderous setting as it's a very vulnerable place for the victim to be in.
