Seth Rogan feels like a sell-out for slimming down

Plenty of Hollywood hotshots have gained or lost weight for a role, but most of them don't start off on the rather chubby end of the spectrum. Seth Rogan, however, did, and while he's lost a considerable amount of weight for his role in The Green Hornet, he's not all that happy about it.

He told E! News, "I'm sellin' out, guys. It's for The Green Hornet. The only reason. There's no other reason. I think it serves the movie." He has no intentions of keeping his new body around for long after wrapping the film, though, saying, "I think it will take three hours [to get his big old body back]."

Even if he's less than enamored with the results, it's taken some hard work to get him to this weight (which he doesn't know, because he doesn't weigh himself) -- he eats well and works out hard. He skips the burgers and visits his "brutal" trainer. "I go there real early in the morning. He tells me what to do, and I go home and go to sleep, and it's like it never even happened."
