Foxcatcher
Channing Tatum really needed to go to a dark place in order to play Mark Schultz for Foxcatcher. Of course, one of the harder scenes was to portray Schultz having his mental breakdown. Therefore, Tatum wanted to fully embrace the scene and decided to beat himself up. Actually, he totally went off script and somehow wound up breaking the mirror with just his head. That entire scene was not scripted. Yet, the resulting scene was so powerful, it was the perfect fit for the movie.
