This is a funny audio clip of Christian Bale going nuts at a Director of Photography on the set of Terminator Salvation. Apparently, this was the second time the guy had just walked onto a really big scene which was being shot and ruined it.
From YouTube :
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.
The scene in question, was a very emotional and tough scene between Christian Bale and Bryce Howard. A scene that required soul bearing and a deep level of immersive concentration. The sort of scene where everyone on set knows not to get in anyone's eye lines, and definitely not to move lights around while FILMING. You lock that shit down before the scene starts.
If you think thats funny, then you may like the dance remix!! ;)
