I was personally a little more interested in THE FIGHTER when Darren Aronosfky was set to direct Matt Damon and Mark Wahlberg but that’s not to say I’m not at all interested to see what David O. Russell was able to bring to the proceedings. Damon eventually dropped out to be replaced by Brad Pitt who eventually dropped out to be replaced by Christian Bale. The film stars Bale as the junkie brother to an up-and-coming boxer played by Wahlberg. In this behind-the-scenes video we get Russell and Wahlberg shooting one of the boxing matches and Wahlberg’s character landing a knockout blow. Check it out below!
