The rules: A movie is named. You exchange an actor, the director, somebody big and present in the movie, with someone who has the same first or last name to the ends of making the movie undoubtedly better or at least really really novel.

So, if the movie is Big, you can replace Tom Hanks with Tom Sizemore. If it's Lord of the Rings, you can swap out Sean Astin for John Astin or Sean Connery, whomever you think would be, at least, more hilarious following Frodo around being blubbery.

And, then you pick the next movie.

The first movie is...

Forrest Gump
