okay, the guy didn't walk into the scene, CB was having a scene with co actor bryce, and the light guy walk in the background behind bryce, therefore in CB line of view, THIS is what CB thought distracting, you can hear him ask the director to tell him something but the director didn't see it, because he didn't walk into the line of sight relative to the camera, CB thought the scene ruined because he got distracted by the movement behind bryce.
Also I believe CB overreacted completely, I mean the guy threatens to beat him up, just because he even tries to EXPLAIN his reason for walking in the background of CB line of sight. Also this is clearly not normal behavior, I mean you can feel that everyone is just in shock at his reaction, and trying to make him chill out, Bale is a good actor, no doubt about it, but he's got anger issues.
