Today marks the release of the Australian crime sensation 'Animal Kingdom' which won the won the Grand Jury Prize for World Cinema at this year's Sundance Film Festival.

After his mother ODs, young Joshua "J" Cody is sent to live with his grandmother and uncles -- where he discovers that his family is a collection of Melbourne's most notorious armed-robbers. Tensions run high as the police ruthlessly begin to enclose the family, putting "J" in danger. He's torn between working with a noble police detective (played by international movie star Guy Pearce) and remaining loyal to his family. But in his family, there's the growing menace of uncle Andrew (played by Australian veteran Ben Mendelsohn) whose quiet, unhinged relationship with his nephew may be the most deadly thing in "J"'s life.

Director David Michod and Ben Mendelsohn talked with Moviefone about the film's international success, the unique performances, and the menacing true story at the heart of 'Animal Kingdom.'
