Breaking the Fourth Wall
A compilation of scenes and moments from films that all “break the fourth wall” – that is, acknowledge (usually directly to the camera, and therefore the audience) that they’re part of a movie. The term comes from the imaginary “wall” at the front of the stage in a traditional three-walled box set in a proscenium theatre, through which the audience sees the action in the world of the play.
