Everyone knows that actors use body doubles, but sometimes the nude scenes look so seamless or the actors are so hot that it is shocking that they used body doubles. Why would they?! Alas, here are some famous movie nude scenes that actually used a body double.

5. Bruce Willis in Once Upon a Time in Venice

Bruce has one of the coolest underwater nude scenes of all time, so it's surprising that his nude scene in Once Upon a Time in Venice was faked. He used a body double for this scene where he runs and skateboards down the street nude. The reason for this is likely that action-star Bruce didn't have the skills needed for this scene.

4. Owen Wilson in You, Me and Dupree

It's honestly shocking to me that Owen Wilson did not go nude at the height of his fame, but this blond hunk appeared to be shy about showing his skin. He has actually never gone nude. That is all to say, that this is not his ass and anytime that you think you are seeing Owen's booty on camera, you are not. Owen owes us his ass!

3. Chris Redd and Quinn Beswick in Deep Murder

This comedy features a good deal of male nudity in one scene from its stars, including Quinn's butt and Chris's cock. An inside source - Redd himself - told me that this is his real ass in the scene, but everything else was done by a very nice body double. And a very nice-looking body double at that!

2. Shia LaBeouf in Nymphomaniac

While Shia sometimes insists that this IS his real erect cock in the scene, director Lars von Trier himself has said that it is not. Sorry, Shia. Not only that, but we have actually seen Shia's penis, so we can easily compare and contrast. This simply isn't it.

1. Sebastian Stan in The Bronze

It is fairly obvious that this was a body double because last we checked Sebastian Stan is not an Olympic gymnast. Stan clearly has no problem going nude, but these in-depth flips and kicks in the flesh were done by another person.
