At the movies this weekend, a twist on the classic story of Snow White and the attack of killer fish in 3D.

A timeless fairy tale returns to the big screen in "Snow White and the Huntsman." "Twilight's" Kristen Stewart plays the young beauty, and Charlize Theron takes on the role of the Evil Queen. The Huntsman she sends after Snow White, played by "Thor's" Chris Hemsworth, instead becomes her protector, and teaches her to fight. "Snow White and the Huntsman" is Rated PG13.

This summer it's still not safe to swim. The bloodthirsty school of pre-historic fish are back in "piranha 3DD." They sink their teeth into guests at a water park, where David Hasselhoff is spending the summer as a celebrity lifeguard. The 3D horror flick also stars Christopher Lloyd and Gary Busey. "Piranha 3DD" is Rated R.
