Back in January, one of the big winners at the Sundance Film Festival was the relatively unheralded Winter’s Bone, which picked up both the Grand Jury and the Screenwriting awards. Now the trailer for the movie has arrived, which gives us our first taste of what excited the Sundance voters so much. The film is about an unflinching Ozark Mountain girl who hacks through dangerous social terrain as she hunts down her drug-dealing father while trying to keep her family intact. The movie is currently set for a UK release on September 17th, but click below for the trailer.
