While the infamous MrSkin.com already published their Best Celebrity Nude Scenes of 2009, we feel it's our duty as cinema experts to choose a list of our own. First of all, our picks are only from film, not Showtime or HBO. Second, we're higher brow, or at least pretend to be, so we consider the artistic merit of the scene, not just "yank factor" (which is exactly what it sounds like).

In addition to arousal and box-office interest, nudity can also be used for humor, shock, vulnerability and dramatic effect. But don't worry, we're not going to go "totally IFC" on you; yank factor is still on the checklist.
