For years you played the lover. Is it more challenging now playing the cuckold?

Why is it always the Brits that use this wonderful word: cuckold? Actually, I have quite a normal life. I have a wife, I've got kids, I have a mortgage, and this is a story about a guy who's also got all of these things. So it was something that, at this point in my life, I felt I could bring something to that maybe I couldn't have ten or 15 years ago.

If your gigolo days really are over, what kinds of roles appeal to you now?

All of them. I keep describing it like falling in love: you can't start a relationship unless there's a spark there in the beginning. I read a script like this and there's a spark. And that's the way it is with pretty much any project that I take on. I've never said, "I'm going play the gigolo now" or "I'm going to play the husband now".

So who's your latest movie lover?

I went right from this into the musical "Chicago", and one of the reasons I probably fell in love with it is because it was so radically different. I think people are going to be surprised. I learned to sing with a Broadway voice, and I tap dance. That was extremely painful, I must tell you. There were days I wanted to chainsaw my feet off.
