"Metacinema is a fascinating, if not particularly well-defined, area of film. For the purposes of our list, at the very least, you can take metacinema to mean a work of film that draws attention to the fact that it is a film. This doesn't mean simply breaking the fourth wall but rather a film that references and examines its own meaning as a piece of cinema. Acknowledging how, when, and why it was made.
This may sound like a laborious subject to understand or appreciate, and that's often what turns people away from it, but there are numerous examples of fundamentally metacinematic movies that are anything but tough to watch. These are our picks for the ten most enjoyable metacinematic movies of all time."
