We may know him best from the TV show 3rd Rock From the Sun and movies like 500 Days of Summer (2009), but Joseph Gordon-Levitt has also given us plenty more than laughs over time. In 2004's Mysterious Skin, he plays a sexually compulsive man who gets his rocks off with another dude about an hour into the film. That's the first (but thankfully not last!) glimpse we got at Joseph's tasty attributes. While it wasn't his only nude role, Joseph's character in Mysterious Man may be his most memorable. He agrees, too. Speaking on his role in the movie, he said, "There's nothing to be embarrassed about." We concur, JGL.
