Walk the Plank.

If you're looking for a matinee with which to beat the heat, avast what you're doing and check out Pirates of the Caribbean: The Curse of the Black Pearl - It's a solid two hours of mindless summer fun. It runs a bit longish, sure, but Johnny Depp and Geoffrey Rush keep it light as Captain Jack "Keef S. Thompson" Sparrow and the eeeevil Barbarossa respectively. (Of course, neither Orlando Bloom nor Keira Knightley are harsh on the eyes either, depending on your fancy.) And it's always good to see Sam Lowry out and about in these trying times. All in all, easily as fun as Finding Nemo, if in the end a little more flawed.
