It is being reported that Kristen Stewart was hurt on the set of “Snow White and the Huntsman,” halting production until Friday.

While details about her injury remain a mystery, her co-star Max Manganello, who plays one of the duke’s soldiers in the film, announced it on Twitter.

The tweet has since been taken down, but Manganello tweeted, “It’s a wrap for today. Kristen has hurt herself … nothing scary. We shoot on Friday.”

Stewart described her role as the iconic fairytale character saying, “It’s not a little girl sitting by a well with little tweety birds telling her what to do and where to go. [The costume] makes you feel kind of strong occasionally, sometimes, but I kind of feel tiny, my pinhead sticks out of these enormous things.”

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.

“Basically, I’m fighting evil – I’m fighting the most evil motherf**kers – and it’s fine that they’re being killed. It’s anguish. It’s literally f**king anguish. She takes absolutely no pleasure in ever hurting anything.”

“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.”

The film is expected to open on June 1, 2012 and also features Charlize Theron (the Evil Queen), Chris Hemsworth (the Huntsman) and Sam Claflin (Prince Charming).
