Who needs a knight in shining armor?

Kristen Stewart's got it covered! On Wednesday the 21-year-old wore full armor and rode her horse into battle for a scene in Snow White and the Huntsman. Her costar Chris Hemsworth also hopped on top of a horse as they filmed on a beach on the southwest coast of Wales.

Stewart's Breaking Dawn costar Taylor Lautner has high hopes for what she'll bring to the iconic role of Snow White. "Kristen's going to be cool and edgy and dark," the Abduction star told the Hollywood Reporter in August. "It's gonna be something new for her, and I think that's really exciting."

Hemsworth, 27, plays the Huntsman, while Sam Claflin takes on the role of Prince Charmant. Charlize Theron plays the Evil Queen in the film. "Trust me, she's dark," Theron said, describing her character at Comic-Con in San Diego. "I'm preparing to play a serial killer. Watch out, Kristen!"

Snow White at the Huntsman began filming in August and is slated to premiere in 2012.
