Tom Cruise Really Letting Himself Go

Just kidding. But if you only had this pic to go by ...

Tom Cruise, who has been promoting his new movie, Lions For Lambs, is back to work on a new project - a cameo in the upcoming comedy Tropic Thunder, directed by Ben Stiller and scheduled for a mid-2008 release.

The nutty father of the adorable little Suri Cruise is believed to be playing a studio mogul in the movie, which also features appearances from Matthew McConaughey, Tom's wife Katie Holmes, and Tobey Maguire.

That's all well and good. But wait until you see this funny photo of a fat, bald and hairy Tom Cruise from the set of the new comedy...
