Jeff Bridges has been cast as Obidiah Stane, presumably as the main villain. There's still talk that the Mandarin will be involved, too, but nothing definitive, and if he is in the film, he hasn't been cast yet, which is unusual. I'm thinking it'll be Stane for this movie and the Mandarin for the sequel. Iron Man doesn't have a ton of great villains, so it makes sense to spread them out a bit.
I'd say Iron Man has a decent amount of villains, but it does make sense to spread them out.
Obadiah Stane
Mandarin
Justin Hammer- I'd love to see a movie that adapts the Power of Iron Man.
Doctor Doom- If they can get the rights for the character, it could really work given the great comic book battles the two have had.
And there are the recent villains...
Extremis- Warren Ellis's best corporate superhero work.
The Iron Man Suit- Possible adaptation of Joe Quesada's "Man in the Iron Mask" Tony Stark VS Iron Man makes for a cool title.
