The images show Stewart's Snow White wearing armour and carrying a sword and shield. The look is in stark contrast to the colourful still released of Lily Collins in Tarsem Singh's rival Snow White picture.
Nick Frost, Ray Winstone, Toby Jones, Ian McShane, Johnny Harris, Bob Hoskins, Eddie Marsan and Brian Gleeson will play the movie's eight dwarfs.
Speaking at Comic-Con, producer Joe Roth compared the fantasy project to Lord of the Rings, saying that audiences can expect an action film: "Our movie, I like to think, is on the scale of Lord of the Rings, in terms of size and scope and appetite - a tough, rough, active male-female picture."
Universal has also released character images of the Queen (Charlize Theron), the Prince (Sam Claflin) and the Huntsman (Chris Hemsworth). Snow White & the Huntsman will open in cinemas in June 2012.
