That's actually a different movie. There are 2 live-action Snow White movies being made. One is "Mirror, Mirror" with Julia Roberts as the Queen, and Lily Collins as Snow White. The other is "Snow White and the Huntsman" with Charlize Theron as the Queen, and Kristen Stewart as Snow White. I just saw the trailer for the Kristen Stewart one today, and it looks really bad. I need to go watch the Julia Roberts trailer & see if it's any better (it pretty much would have to be).
Sayhello
Added: OK, I just watched the trailer for the Julia Roberts one, and it looks really cute. Very tongue-in-cheek. It opens March of 2012. The Kristen Stewart one comes out in June of 2012. How odd, 2 Snow White movies so close together.
