Two points, I met Christian Bale a couple of times back in 2000 on a film he made in Ireland, he was a gent then, and he rescued a stray dog, that was adopted by the 2nd unit production manager.
Okay yes, this was a fucking temper tantrum of the highest fucking order, but as I understand it, this DoP likes to change the lighting rigging mid shot. Now firstly this is bang out of order for DoP to do, ith's just not done. And early in the rant he says that he's objected to this before. On a film set, turning a take, and keep in mind I've, like PK, been on 100m dollar film set, once the camera is rolling, you don't fucking dare breath when cameras are rolling. Never mind make eye contact with an actor, never mind move around and switch lights, it's just not fucking done. Same as you don't dance around in the wings of the RSC in clown makeup stark bollock naked mid performance, you don't do what this dipshit did, mid performance. You're crew, you slay yourself to ensure the cast can focus on performance.
Like I said around a decade ago, I worked on a movie with christian bale were he was a polite gent, and rescused a stray puppy, this week, he acted like a dick on a massively big budget movie, when his DoP was totally out of line.
Essentially you witnessed a man freak out over his pint getting spilled without some perpective. Me personnally I could never act. Ever been on a film set? My wife is watching Secretary at the moment, and I know during the most intense scenese 30-40 people are watching and about another 10 people get uncut dvds of the uneditted performance.
Christian Bale is pretending to be a freedom fighter aganist an army of robot killing machines, and is trying to give some emotional intensity to a scene most of us couldn't act more wooden in if we got a complete maghony organ transplant.
