Chris Hemsworth, Esquire

We've all seen Chris Hemsworth's ridiculously ripped body in Thor.

But the 29-year-old Aussie actor actually had to lose some of that muscle (say it ain't so!) to play Formula 1 racing star James Hunt in the upcoming movie Rush.

"Thor is large," Hemsworth tells the latest issue of Esquire. "For that I had to add some muscle, which hasn't been all that hard so far. I like training just fine, thanks. But to play a Formula One driver, I had to drop quite a bit of that. You know, slim it down."

He continued, "First time I looked at a Formula One car in person, I just stared at the cockpit, figuring I'd never get in there. The drivers wear the whole car like a tight-fitting suit. So I just started training differently, shedding all that Thor. I've come to see size as just a kind of prop."

As for getting into the character of a famed car racer, Hemsworth says, "I grew up in a culture of motorbike. So I like racing just fine. Quite a lot, actually. That was when I was a boy in Australia. And I never really made the jump to cars after that."
