Robert Downey, Jr. is Iron Man

Robert Downey, Jr. is suiting up to star in "Iron Man," a superhero movie based on the Marvel Comics character.

Jon Favreau is directing the Paramount Pictures release. Filming is slated to begin in February in Los Angeles.

Marvel president of production Kevin Feige said the filmmakers looked for the best actor to embody the character.

"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.

"In every casting announcement we’ve done, people in their mind’s eye have their own view of it and let us know about it. We’re used to it," Feige said. "The point is, we looked at everybody, and we found the best person for the role. It’s as confident a casting move as we’ve ever done. The proof will be in the pudding, but he is Tony Stark."

Downey returns to theaters on November 10 in the Diane Arbus bipic "Fur" opposite Nicole Kidman.
