What? That's not enough?
Feh. If you listen to the tape you hear Bale say the DP had been asked multiple times to stop messing with the lights and stay out of his line of sight while cameras were rolling.
So why didn't he?
Ain't It Cool News has a report on the story, confirming that most crew members on film sets would never behave in the way the Director of Photography on Terminator was:
The DP on TERMINATOR SALVATION, Shane Hurlbut, is a apparently a light tweaker. He's a fairly young DP and likes to fiddle with his lights on set during action, which is a big "NO NO" on most productions unless worked out in advance with performers. But apparently Shane was a pretty unrepentant light tweaker. ...
Bale had indeed warned the DP on multiple occasions about messing with lights while the cameras were rolling, and Bale was in the midst of a painful scene with Bryce, what was described to me as being the emotional center of the film and his character for the film.
Someone should have taken the DP aside and told him to cut the crap before it caused a fit. Instead, they released this audio and tried to damage Christian Bale's career by making him look like a prima donna.
