Breaking the 4th Wall Movie Supercut
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.
The montage includes 54 different films (some used more than once) from perhaps the very first example of breaking the fourth wall right up to today. There were so many other great examples I couldn't find room for (sadly, The Dude and The Big Lebowski's narrator don't abide here), I'd love to hear which 4th wall breakers you'd also include.
