May God have mercy on this shark

Let's just agree that Snakes on a Plane is not only the most brilliant high-concept four-word pitch in the history of movies, but also the best title ever. It was actually only the working title, but when they tried to change it, star Samuel L. Jackson put his foot down. "We’re totally changing that back," he said. "That’s the only reason I took the job: I read the title." And he's right. It sums up everything. You know what you're getting. "You either want to see that, or you don’t," says Jackson. A poster on the IMDb message board insists that the movie must contain at least one instance of Sam Jackson shouting, "There's a muthafucking snake on this plane!" I think every single line of dialogue should consist of Sam Jackson dropping the MF bomb and shouting some variant of the film's title. Because it's the best title ever, for what is guaranteed to be the best movie ever. It just doesn't get better than Snakes on a Plane.

Clearly, it's a race for the silver at this point. But I think I might have hit on a contender while trying to combine an old girlfriend's two favorite genres of scary movies. Are you ready? Here it is:

Shark Exorcism.

A great white shark is possessed by the Devil and terrorizes a small seaside community. A lone priest must don mask and scuba tank to do battle beneath the waves against powerful, unearthly forces. A town's future—and a shark's soul—hang in the balance. This summer ... may God have mercy on this shark. Shark Exorcism.
