Certainly Bale went a little overboard with the rant, I think no one will argue that. But I'm not going to be so quick to throw him into the Michael Richards pit, that'd be going too far. Alec Baldwin survived his rant, I think Christian Bale will be fine too. If you're curious to read an account of what caused the outburst, go here.
Feb. 6th update - Bale calls into KROQ radio. There's a little play button near the top of the screen.
