"Iron Man 2" is a topic of conversation, as he and Favreau are currently collaborating on a story for the much anticipated sequel. "Now Justin Theraux who wrote 'Tropic Thunder', is writing it and Jon and I are working on the story with him. It's pretty great and I think it's going to be cool. I think it's going to appropriately well thought out so that we don't forget what got us the response that we appreciated so much, which is, we didn't say, 'Great, now that this is like this, now we're going to twist it and do this with it.' It's now; I'm not saying we're going to do bits. I think more of the same; it is a very rich feel, because it was a very simple movie, if you ask me. It was an origin story."

Which apparently was not the case with the other big summer movie "The Dark Knight". "My whole thing is that that I saw 'The Dark Knight'. I feel like I'm dumb because I feel like I don't get how many things that are so smart. It's like a Ferrari engine of storytelling and script writing and I'm like, 'That's not my idea of what I want to see in a movie.' I loved 'The Prestige' but didn't understand 'The Dark Knight'. Didn't get it, still can't tell you what happened in the movie, what happened to the character and in the end they need him to be a bad guy. I'm like, 'I get it. This is so high brow and so fucking smart, I clearly need a college education to understand this movie.' You know what? Fuck DC comics. That's all I have to say and that's where I'm really coming from."

Well clearly Downey isn't about to do anything for DC Comics anytime soon. "You know, you're never too old to burn your bridges because I believe I have offended everyone," he says, laughingly. "I think I've got a couple more. 'I'll burn that bridge when I come to it' is my favourite phrase I've ever coined."
