Most people assumed as much, but Favreau pretty much makes it clear in a new interview that War Machine will be in the Iron Man sequel.

"Rhodesy is definitely stepping up in this film," Favreau said. "Let me put it this way: Tony's not the only person with technology in the film."

Rourke also talked a bit about his own experience filming the movie and talks about his armor that he'll be wearing himself.

"I'm having the time of my life!" he said. "It's been really brutal, because my Iron Man suit weighs 23 pounds. It's sort of a half-suit, with half my skin showing, with lots of Russian tattoos, because [Whiplash is just] out of a Russian-zone prison."
