To me, Jason Statham (46 this week) is the new Vin Diesel. Both are big, bald and play badass great. Vin seems to have gotten out of the action hero biz, which leaves a gap that needs filling. And Jason does so quite nicely. He doesn't have the mixed ethnicity going for him like Vin. But there is the British accent, and that helps for sure. See more of him at Superherofan and Tumblr.
Chandler Massey turns 23 this week. He got my attention (and lots of others) for his portrayal of a gay teen coming out on DOOL. Even won an Emmy for it. Maybe because they were trying to be more serious with the storyline, the show cut down on his shirtless scenes.
