Let's face it, as entertaining as the "Iron Man" movies have been thus far (okay, the second one not so much), the villains haven't been all that great. The first was a game but not particularly memorable Jeff Bridges as the duplicitous Obadiah Stane, the father of Tony Stark's old partner. Shrug. Then in the sequel there was the double dose of the wildly ridiculous Ivan Vanko, played by Mickey Rourke, and the pitch perfect but underused sleazebag Justin Hammer, in a part taken by Sam Rockwell. But the third in the franchise could be the charm.
