Robert Downey Jr. wouldn't wear his 'Iron Man' suit.

The 45-year-old star - who plays the comic book hero in the film's two instalments - says he wouldn't like to don the special superpower suit himself even if he was given the chance.

He said: "I think it's the one that people are most likely working towards. I attempt to live in reality as often as possible, fantasy is fun but then you wake up. So I don't know, I think if we were supposed to have those powers people would have them."

Robert also claims he is like his 'Iron Man' character Tony Stark in real life.

He told website Movie Hole: "I'm a California resident, I'm like Tony Stark you know, I live by the beach, I have a nice spread, I'm a lucky guy but I realize more and more it's not just important it's crucial I get out and travel more and understand more about other cultures and people and how we've all shaped the world together. I have such an incomplete education."
