We know Christian Bale is a little intense on screen. Audio footage now proves Bale carries his persona off-screen, as well. E! has released audio of Bale flipping out on the set of Terminator 4: Salvation. His tirade, which includes several F-bombs, is aimed at the movie's director of photography who he felt ruined a scene. T4 directors recorded Bale's diva fit for insurance reasons because it included a threat to leave the project. They later stated that Bale just had "a bad day" and that he is "a consummate professional."
