I think people should stop viewing actors through the lens of normalcy because they are under nothing but extraordinary circumstances. What I like about Christian Bale is that not only is he a good actor but, like us, he has his vices and issues. Are you trying to tell me you've never blown up at someone?
+1 on context (what happened before the clip, the money being wasted by the messed up shots, his personal life, etc).
People need to stop caring about celebrities personal lives so much and worry about their own.
