"He's Iron Man, he's Tony Stark, he's going to go a million miles an hour," Favreau said in an interview with The Los Angeles Times.
"So what do you expect this film to be and how can we take it past those expectations? When I was watching AC/DC with my wife and my son and they were playing 'Shoot to Thrill' at the Forum, I thought, 'You know this is how he should show up, right in the middle of this and take the armor off. That's the Tony Stark version of doing things."
"It was a big leap," he added. "It was not a cheap thing to do. Whether you're blowing up a tank or landing in a rock concert, it's the same thing for a visual-effects team, once he's moving around, he's moving around."
Iron Man 2 is set to be released on April 29th in the UK and May 7th in the US.
