It's James Cameron vs. Kathryn Bigelow!
Alas, though I'm desperate for their golden competition to turn into the most bitter battle royale since Olivia deHavilland and Joan Fontaine, there seems to be a frightening amount of good will brewing here. In fact, Cameron and Bigelow are friends (Their split was way back in 1991) and he's even the one who advised her to direct The Hurt Locker when she was focusing on some other project!
Still, let's get a little bit common-sensical for a second. Even if there's not much animosity between these two anymore, it must be galling to compete with your ex spouse for a Golden Globe (and then there'll be the DGA and the Oscar and God knows what else).
No matter how much affection might linger, it has to be the most awful thing on earth to risk losing an important trophy to the life partner you dumped! It's like having someone run you over, then take your limb 20 years later!
I mean, if an old boyfriend of mine beat me for the Oscar, I'd beat him WITH the Oscar.
Kidding. I'd applaud wildly, then run home and vomit myself to sleep.
