It's a tale of two action movies. The first: "Mission Impossible: Ghost Protocol." While filming recently, Tom Cruise repelled down the tallest skyscraper in Dubai, making his way from the 113 to the 112th floor. That's him in the photo on the right, dangling about 2,000 feet off the ground. "I want to entertain the audience and part of making these movies is doing my own stunts," Tom said. "I love having the camera right there in front of me, where you can see me holding a shot all the way through." [Daily Record]

Now let's contrast this with Shia LaBeouf, who filmed a scene in "Transformers: Dark of the Moon" on Monday. To capture a similar scene, Shia slid down a slide made to look like the windows of a skyscraper. [NY Daily News]

The honest truth is that most celebs don't do their own stunts because (a) they're wimps (b) they're sane or (b) it costs so much to insure them that it's out of the question for most productions. But in Tom's honor, here's a look at other celebrities who aren't scared of hurting their million-dollar bods.
