Kristen Stewart is injured on set

The shooting schedule for Kristen Stewart’s latest film suffered an unexpected hitch earlier this week after the actress injured herself on set.

Kristen, 21, has taken time out from all things ‘Twilight’ to film fantasy epic ‘Snow White and the Huntsman’ with a star-studded cast including Bob Hoskins, Chris Hemsworth and Oscar-winner Charlize Theron – but an accident on set has resulted in production grinding to a halt until Friday (Oct’ 21st).

Writing on micro-blogging site Twitter, cast-member Max Manganello confirmed Kristen’s injury – which he descried as ‘nothing scary’ – but later removed the Tweet without explanation.

Speaking to Box Office magazine earlier this month, the actress spoke of the challenges she faced in taking on her new role as a warrior princess in the forthcoming film - believed to be the first in a trilogy. 

"Not to trivialize it at all, but it's hard to play an action hero who is also the most compassionate person on earth," she said. "You can't hate. You epitomize bleeding hearts, so how the f**k do you do an action movie like that? She is sort of the last shred of hope for her land."

With the physically demanding nature role representing a significant departure from characters such as Bella Swan, Kristen admitted to being drained by her extensive fight scenes. 

"Basically, I'm fighting evil - I'm fighting the most evil motherf**kers - and it's fine that they're being killed," she said. "It's anguish. It's literally f**king anguish. She takes absolutely no pleasure in ever hurting anything.

"I'm exhausted right now and I was thinking, "The fight stuff is coming up, maybe that won't be so bad." And then I realized that they're probably going to be my most emotional scenes because I'm killing people and I'm Snow White.

"It's a really f**king cool way to approach a movie where so many people die. Not that I'm criticizing violent movies - I love them, generally - but it is nice to do it this way."
