Chris Hemsworth Is In Physical Pain, And It's All Our Fault

Sorry, buddy.

Besides the insanely amazing "Avengers: Age of Ultron" clip that debuted during the MTV Movie Awards on Sunday (Apr. 12), our favorite part of the Awards was when the Avengers gang themselves took a knee onstage to present Tony Stark himself, Robert Downey Jr., with the Generation Award. So when MTV News caught up with Chris Hemsworth backstage, we just had to ask what it was like to pay tribute to the hero that started it all. And, apparently, it was pretty painful.

"It was kind of uncomfortable, I'm not going to lie," Hemsworth said. "I've got a bit of a sore ankle, currently."

So that's Thor's Achilles Heel -- kneeling on one knee. Got it. Luckily, there are no hard feelings.

"It was worth it; he's worth it," Hemsworth said. "He's an incredible guy. He's the godfather of the Avengers and the Marvel universe for all of us. He started this, we followed, so it's the least we could do."

As for all of the positive buzz for "Ultron," Hemsworth just said he's thrilled to be a part of it.

"We're all just small pieces of the giant puzzle that [director] Joss [Whedon] and the Marvel guys have created," Hemsworth continued. "To hear people say it's possibly their biggest film of all time... it's insane. I pinch myself through this whole process."

One thing Hemsworth is not happy about, however, is being snubbed in our Best Shirtless Performance category year after year after year.

"You keep nudging me out for that one," he said with a laugh.

Your move, Efron.
