Intertextuality is a term used to describe visual referencing between films. Most times films tend to 'borrow' from eachother. This is usually done depending on the genre of the film. Many horror films for example tend to borrow the opening of a 'haunted' 'creepy' house and the weather being 'a dark and stormy night'. Although it is not only the setting of films that are 'borrowed' from one another. Some films may copy some areas of mise en scene, snippets of sound or techniques in editing. An example where intertxuality is used is within Fatal Attraction. The shower scene that is originally in Psycho is used in Fatal Attraction both the type of shot and the white tiles and curtains within the shower. Furthermore both women are in shock/shrieking because of the attacks they are recieving.
What interests me the most about intertextuality is that film makers can take elements from other successful films and add them to their film to further that success. Furthermore the continuation of takng particular forms of mise en scene, camera angles, or snippets of sound e.g broken glass or openings of creepy houses can be turned into essentials for thriller films which helps the audience identify the type of film they are watching. Finally by using intertextuality I think it creates a link between films in the 70s earlier or later and films of today, which creates a bigger culture for the film industry.
