Kristen Stewart loved being a "nutcase" on the set of her newest movie, but also appreciated the "big group hugs and cuddles" in between.

The actress stars in fantasy action movie Snow White and the Huntsman alongside Chris Hemsworth and Charlize Theron.

Kristen loved getting down and dirty for the high octane big screen role, but admits comforting cuddles were welcomed too.

"We're nutcases I think we really loved it," she told the Kyle and Jackie O radio show, before laughingly adding: "Just big group hugs, time for cuddles!" when asked if they got hot blankets in between takes.

"There was a sick sort of enjoyment about it, it was wet, cold and freezing but it was like a school camp where you're thrown in it for four months in some obscure location," her co-star Chris added.

Charlize stars as the evil Queen Ravenna in the big screen reimagining of the classic fairy-tale. Kristen loved working with the Hollywood star and she learnt a lot from her on set.

"I found that me and Charlize had a real love/hate relationship and it was good. When we were not on set we got on really well. It's exciting to be around her," she gushed.

Chris was in awe of Charlize's work ethic. The Australian actor says the blonde beauty's approach resonated throughout the whole cast and crew.

"You know when she's on set because it's intense, and I only did one scene with her," he said.
