There's a pecking order on every set. It doesn't sound like McG had control of his set, which obviously reflects negatively on him. If the DP was indeed being a distraction, then McG should have been aware of it, and pulled the DP aside and had a chat with him - especially considering that this was the second time he did it, according to Bale's rant anyway.

But that aside, McG should have done much more to assert himself, instead of allowing Bale to continue on for as long as he did. That kind of behavior could be very disruptive on any set.

Obviously, Bale is the STAR (caps intended). But, again, if the director had full control of his set, this kind of shit wouldn't happen. Imagine if this was a veteran director behind the camera; I know disagreements occur on sets all the time, but, I doubt that this particular scene happens on a Soderbergh set; or a Clint Eastwood set; or a Coen Brothers set; or a Scorcese set; or a Spielberg set; etc, etc, etc...

So, I blame McG for the entire thing.
