Animal Kingdom (2010)

In this gritty Australian crime drama, young Joshua "J" Cody (James Frecheville) is taken in by his extended family after his mother dies of an overdose. This branch of the Cody clan, overseen by J's scheming grandmother, Janine (Jacki Weaver), is heavily involved in various criminal activities, and they quickly indoctrinate the boy into their way of life. However, J is given an opportunity to take a different route when a cop named Leckie (Guy Pearce) seeks to help him leave the family fold.
