If the third movie was better than it had any right to be, the fourth film isn't nearly as lucky -- and that's because it's a loud movie that doesn't have a lot to say. In fact, if there's anything to be learned from "Terminator Salvation," it's that a) McG likes to blow stuff up, and b) Christian Bale, who plays resistance leader John Connor, likes to shout -- a lot.

"I do every movie because of the director," the 32-year-old Australian told Access Hollywood. "McG - he's such an enthusiastic, passionate [director] that he was the reason I signed on."

"It broke my heart, because I take all the responsibility for protecting my actors on the set day in and day out, and it's my responsibility to make sure that they can be free to express themselves in anyway they like and it's a real violation of the family of the set community," the director told Access Hollywood's Nancy O'Dell about the release of the audio where Bale is heard ranting against Hurlbut.

"The DP on 'Terminator: Salvation,' Shane Hurlbut, is apparently a light tweaker," Ain't It Cool editor-in-chief Harry Knowles reported on Tuesday. "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. But apparently Shane is a pretty unrepentant light tweaker."
