Intertextuality is when films borrow certain parts of another film. I think Intertextuality is quite interesting. The way films have the same sort of idea, placed in a different way is intriguing as you dont always notice, unless it is pointed out. An example of textuality is in the films; What Lies Beneath, The Stepfather, Fatal Attraction, and a student film called Succubus. Each of these films have taken some aspects of the film Psycho's shower scene. Below i have posted a link to each of these videos.
