Intertexuality.

Intertextuality is basically the relationship between texts, or in this case between Films.It can refer to a director borrowing scenes from another film to transform or pay hommage to that particular film that the scene was borrowed from.
- a good example is, Fatal Attraction. There was a scene in Fatal attraction which was influenced by the pivotal 1960 film Psycho, within the climax of the film, the film's antagonist Alex appears in the bathroom and attacks Beth (Dan's wife who also had an affair with Alex). We see Alex stabbing Beth multiple times à la Psycho. Also Dans rips the shower curtains from their hooks when he falls into the bathtub. When Alex is shot she slowly collapses down the wall, like in Psycho after the women has been stabbed. In both films the women that kills the other is in a bathrobe.
