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."
