“Breaking the fourth wall” is a creative device used when a character addresses the audience or otherwise acknowledges that they are in a work of fiction. It has been used by many authors over time, from Sophocles to Shakespeare to the writers of Deadpool. In 1965, the Daffy Duck short “What’s the Big Idea” presented the famous character berating his animator for placing him in increasingly nonsensical and degrading scenes and costumes.
