Intertextuality

Intertextuality: The visual referencing between films where aspects of the film are practically borrowed, revised and reused. You may recognise certain camera angles, sounds, editing technics and mise en scene that were used in the film it had been borrowed from.

My favourit style of intertextuality is when a extremeley good film is taken by a film company and revised into a more comic form.
An example of this would be say taking an film like 300 and turning the storyline of the film into a comdey because although it is not as serious as the actual film it still gets the pinot across.
