Last summer, Christian Bale went to extreme measures (again) to physically prepare for a role. Now, we get to see the film he was so passionate about.

In The Fighter, Bale plays a Dicky Eklund, a former boxer turned drug addict who later helps his brother (Mark Wahlberg) with his own career. The biopic about real-life boxer “Irish” Mickey Ward (Mark Wahlberg) also stars Amy Adams Mickey’s love interest.

The movie, directed by Three Kings’ David O. Russell, opens on December 10—just in time for Oscar season.
