The only thing more shocking than the brilliant twist endings of M. Night Shyamalan's landmark films is the fact that our beloved Paul Giamatti has agreed to endure one of the brilliant twist endings in one of M. Night Shyamalan's landmark films.

That's right: Giamatti has reportedly agreed to star in Shyamalan's Lady in the Water, in which he'll play a superintendent who finds a sea nymph in the building's swimming pool.

Little else is know about this film; there's even a rumor that it might finally break from Shyamalan's habit of ending his movies with fantastic, breathtaking, totally unbelievable and sometimes quite retarded plot twists. But we know Shyamalan better than that, which is why we've handicapped the potential Lady in the Water shockers. Warning -- spoilers below! We're sure of it!
