It's going to be a battle of the exes in the Golden Globes' Best Director race. In this corner: director of the most expensive movie ever made (twice!), Oscar-winner, and self-proclaimed King of the World - 'Avatar''s James Cameron!

And in this corner: action-filmmaker extraordinaire, director of 2009's biggest critical darling, and possibly the first woman ever to win a Best Director Oscar - the former Mrs. James Cameron, 'The Hurt Locker''s Kathryn Bigelow!
