4. The Baddies
William Hurt plays General 'Thunderbolt' Ross, the tough serviceman obsessed with capturing the Hulk. It's a role that needs a blinding explosion of fury, and Hurt -- one of the finest character actors around -- can turn up the heat enough to even scare the Hulk into lime-green.
And then there's Emil Blonsky, who becomes the Hulk's nemesis, Abomination. It's an insane supervillain role, that of an aging soldier who transforms into a gigantic monster, but tackling it is none other than Tim Roth -- and Tim Roth always rocks. Always.
