Like everyone else, I thought this audio leak was hilarious and I loved the remixes. But one thing I will say in Bale’s defense is that I think the DP is a douchebag for walking into a shot. It sounds to me like a selfish power play on the DP’s part — walking into the shot renders the take useless.
The only reason someone would want to do that, is so that whatever they didn’t like about the scene wouldn’t be used. As the director of photography, that is not his call. That is why there is someone on set called the director. By walking on while the cameras are rolling, he wasn’t thinking about anyone else’s contribution to the film e.g. the performance, the crew, etc. It’s similar to stupid tricks that shitty actors pull so that they can get more screentime. Like I said, the DP sounds like a douchebag and he probably deserved the tongue lashing.
