The Simpsons

The primary cast all have agreements in their contracts that hold them to doing three movies based on the show in the future.

According to a Simpson Family tree designed by Matt Groening, Mr. Burns is a distant relative of Homer.

The creators jokingly insist that they have parodied 'Citizen Kane' so much that one could re-create the entire film solely from Simpsons clips. They also have made the same claim about 'The Godfather' and 'The Godfather: Part II'.
