Robert Downey Jr. says he has a good day when he gets to beat people up.

The actor urged writers and the stunt department of Iron Man 2 to give his character more action scenes because they are his favorite to film.

“The action’s certainly got bigger because I went to do Sherlock Holmes, which was a real adventure. So coming back into this I really challenged our stunt team to get our hands dirty a little more because I was still kind of into that… I love it so much. There is no better day that I can have than one where I beat people up or get thrown around. I just love it. It’s supposed to be safe, but it’s a little more than acting so it’s really fun.”

The actor also admitted he always believed he would be more successful than other people expected: “I always had a huge confidence in myself and saw myself having a far better career than anyone thought. Not in an unrealistic, narcissistic kind of way, I just think I was always irrationally optimistic about it.”
