I love a good fourth wall break, when someone in a show or film turns and speaks directly to the audience, or into the camera. When done well, it creates a more intimate relationship between the actors and the audience.
Here’s a bunch of examples of doing it well.
Annie Hall is my fav but Ferris is a close second.
If only they had used the ending of The Omen in the unsettling part instead of The Wizard of Oz.
