Intertexuality

Intertexuality is a term to describe the visual referencing between films. It includes texts that refer to other media texts that producers assume that audiences will recognise. Intertexuality describes that films borrow from each other, and as the audience we may recognise certain things. Examples are they may recognise certain camera angles, aspects of Mise en scene, sounds or methods of editing in some films that you have seen in others. Various films are made together to give a different film/message. Example of films are Shrek, scary movie and Simpson and many others that have borrowed from films. This make the audience feel more involved and also recognise these aspects, and makes it more familiar.
