Intertextuality

Intertextuality  are scenes in which parts of some the conventions are borrowed from different films, such as in "what lies beneath" we hear the same water shower as of "Psycho". also in "Fatal attraction" we see the stair case and then in the bathroom we see a knife, which we also see the stair case in "The Stepfather" and we also see the mirror shattering on the floor, and just like in "Psycho" we see the curtains falling in the bathroom.
Intertextuality usually appear in thriller movies.
