Robert Downey Jr. Bulks up For Iron Man

"That's the funny thing. People say, 'How is your son affected by your big self important narcissism?' and I go, 'He's not thinking about me!'” Downey told Extra.

Downey had to bulk up for the Iron Man part and used a combination of exercise and creatine. “I'm a big martial arts guy. but as far as looking good on screen. I started taking this creatine from Sweden. It's a legal thing. People say it [creatine] bloats you. So you are putting on size, but you also look like you just ate five strombolis. But this stuff is non-bloating creatine. When I was taking it, I looked really jacked and then four hours after taking it, I looked like a shrunken monkey again. But I also worked my a** off doing it!"
