This year this category is full of very strong contenders this year with no clear front runner.
Mickey Rourke. There's the chance that Sean Penn could upset this as he's gotten a lot of praise for his Harvey Milk, and Langella is the dark horse here, but everyone has just adored Rourke this awards season. He's quirky, he gives crazy acceptance speeches, and above all, he freaking deserves it. I think the Academy will do the right thing here.
Who Should Win:
Mickey by a mile.
