'Winter's Bone' tops Sundance

'Restrepo' takes home U.S. doc grand jury prize

Debra Granik's "Winter's Bone" was the big winner in Park City Saturday night, as it won both the dramatic competition grand jury prize and the Waldo Salt Screenwriting Award at the 2010 Sundance Film Festival. Earlier in the day, the gritty drama secured North American distribution through Roadside Attractions for release later this year.
