Intertexuality is the term to describe when certain aspects or ideas are borrowed by one film from another, sometimes being used as a parody. The example I'm going to use is the famous shower scene from 'Psycho.'

Since it's release in 1960, that shower scene from Psycho has become one of the iconic and most memorable moments in the history of cinema. Similar scenes have been recreated in many films, mainly in the horror-thriller genre. Below is a still from the original film as the killer is about to stab the woman to death.

       The still below is from The Stepfather; as we can see, they have used intertexuality by recreating the stance of the killer. Also, although this scene is not set in the shower, they have kept some of the originality by using the same prop (a knife) and having a stereotypically male killer and a female victim. However, it dffers from Psycho because she manages to survive by killing him and his bleeding body is left lying on top of the bath, similar to how the blood of the victim in Psycho mixes with the shower water.                                                                           Another movie that has used some aspects from Psycho is Fatal Attraction. They have also used the same setting and mise en scene as Psycho in the shower and this is where the main event takes place, although they have gone against conventinal horror-thriller films and have used a female as the lead villian rather than male. Again, the knife is used as the weapon, the same prop and visual aspect from Psycho. Despite the female character being portrayed as the murderous villian, the male lead eventually saves the other woman and kills the villian, restoring the view of men being masculine, powerful heroes The combination of the use of diegetic sound of the woman screamimg and the non diegetic sound of the violins contributes to creating a suspenseful, chilling and ominous atmosphere.
