I don't know if you've heard this prize bit of off-camera nonsense, but basically Christian Bale on Terminator 4 goes ape shit because apparently the DP was moving around or something during a scene.
I'm not one to trivialize what actors do, certainly, especially the good ones (of which he really is not), but if I were a director and someone did this, I'd do my best to see that they were fired. I don't care what happens, nobody talks to each other like that in a collaborative work environment. He was an asshole because he could be. If it were a set decorator, he couldn't get away with talking to an actor like that. That's bullshit.
And what kills me is the comments of people on that YouTube thread that actually defend him. What the fuck? When is it every OK for people to be assholes like that in a work environment? He's a fucking actor, not someone curing cancer.
What a dick.
