Our action-packed lead-up to the 2012 MTV Movie Awards kicked off in a big way Tuesday (May 29) with our first Sneak Peek Week screening, of "Snow White and the Huntsman."

Not only were we able to present an exclusive clip from the highly anticipated film and screen it for a very lucky and enthusiastic audience, but stars Kristen Stewart and Sam Claflin were also on hand for a lighthearted-but-juicy Q&A, during which they revealed the pain and gain of their arduous-yet-rewarding experience.

"I think it was way more about getting ready to go through hell rather than learning fight sequences and stuff," Stewart said. "Every time I learned something, it was so not right [for the character]. Everything that I do in the movie, I could physically do."

For Stewart's co-star Claflin, who makes an impressive entrance in the film as the dashing and very skilled archer William, the actor was happy to have seasoned action star Chris Hemsworth around on set for guidance.

"For me, I had Chris Hemsworth to look at constantly," Claflin said of who he modeled his character after. "Way to make you feel less of a man. I think the producers wanted me to be him, but he couldn't play both parts. I was training quite a lot. One day I was on set when he took his top off and said, 'Can you hold this?' and [his stomach] is literally an ironing board," he joked, before admitting that his training was not at all easy. "It was hard. It was very hard work."
