Maybe you've heard of film director Joseph McGinty Nichol, popularly known as "McG." Perhaps you'd like him to get beat up, if only because he calls himself McG? If so, don't fret—-Bill Murray already did it.

McG, director of such films as Charlie's Angels: Full Throttle and Terminator Salvation, doing press junkets to promote the release of Terminator Salvation, was talking about Christian Bale's much-publicized freakout during filming and how movie sets can be stressful environments filled with monster egos, when he casually mentioned this little story to a reporter from The Guardian:

McG declines to comment any further than he already has, but points out that movie sound stages can be stressful places where creative battles sometimes become heated. Particularly, it seems, on his sound-stages. "I'm reintroducing the fist-fight to movie sets," he smiles. "I don't think there's been a film I've made where there hasn't been some kind of physical fight. I mean, I've been headbutted by an A-list star. Square in the head. An inch later and my nose would have been obliterated." Will he be revealing any names? "Nah, I probably shouldn't," he smiles. "But it was Bill Murray. Y'know, it's a passionate industry."

Bill Murray?!?! Bill Murray is a lot of things, but he might be the absolute last guy we'd ever expect to throw a headbutt on a director during filming. Do we see him sipping cognac and playfully flirting with younger women in hotel bars, accosting people in the middle of the night in parks, and maybe wandering into a hipster party in Brooklyn and getting stoned with the kids every now and again? Yes, totally! But do we see him as someone who headbutts people at work? No, absolutely not, which all points to one thing—-McG is probably as massive a tool as his name suggests.
