Actually, Snakes on a Plane is a real movie starring his Die Hard With a Vengeance co-star Samuel L.! The studio wanted to change the name, but Sam said, "No way! The title is the only reason I even took this role! Snakes on a Plane, man!"
ROTFLOL.. that brought a tear to my eyes.
Still laughing. I read on imdb the following plot outline-"On board a flight over the Pacific Ocean, an assassin, bent on killing a passenger who's a witness in protective custody, let loose a crate full of deadly snakes."
I just saw Flight Plan. Maybe this one will be even better.
