Iron Man's nemesis Obadiah Stane (Jeff Bridges) tied with The Incredible Hulk's Emil Blonsky (Tim Roth) and The Mummy: Tomb of the Dragon Emperor's Dragon Emperor (Jet Li) for third place, with one per cent each.

The end-of-summer Moviefone.com poll was another big winner for The Dark Knight, which has made a total of $502.4 million at the U.S. box office-- it also won in the categories for Best Sequel, Best Superhero Movie, Best Action Sequence and Movie Most Worth Your Cash.
