Intertextuality is when films take elements of other films to use in their own. These elements could be mise-en-scene, camera angles, sound or methods of editing. Examples of intertextuality can be found in the film "What Lies Beneath" which took aspects from the film "Psycho". Similarity in mise-en-scene includes a white bathroom environment and similar sound such as running water. "What Lies Beneath" also uses intertextuality in terms of camera, as it uses a similar panning shot.
