Kristen Stewart dons armor and wields a huge sword and shield for her next movie. Rest assured, it will not be your mother and father's Snow White. Stewart joined other cast and crew Saturday at the Comic-Con fan convention for a preview of next year's “Snow White and the Huntsman,” an action-packed twist on the fairy tale. The “Twilight” star told a Comic-Con crowd that doing a sweet, traditional Snow White was not something “I was jumping at.” What attracted her was that this Snow White was a bold leader with her feet firmly on the ground.
