I like Robert Downey Jr., and think he could work well as Stark.
"The Marvel characters are not just about how high they jump or how fast they fly, they're about their character flaws," Feige said. "They're about their inner demons. They're about the struggles that they go through between being a man and being a hero." Downey, who has battled his fair share of inner demons, worked hard to get the role, getting in shape and even growing a goatee like the one Stark sports in the comic books.
