Forrest and Mac in "I Hope They Serve Beer in Hell"

Tucker Max, who wrote a book by the same name about his drunken sexual exploits, is now filming the movie version. He somehow recruited UFC light heavyweight champ Forrest Griffin and UFC lightweight fighter Mac Danzig to play cops in the movie.

Forrest was a cop for a few years in Athens, Ga. And Danzig probably could've been one, he's so strict about his lifestyle, being a vegan and all.
