Dubbed Dr. Iron Fist (he has a Ph.D. in sports science), the Ukrainian heavyweight, 31, fights Lennox Lewis on Saturday.
SI: Do you like Lennox Lewis personally?
Klitschko: He's a cool guy. We met during the shooting of Ocean's Eleven, where my brother [Vladimir] fought him [it was part of the script]. I can't say nothing bad about him.
SI: You've said you would never fight your brother. How about for $50 million each?
Klitschko: Fifty million to kill my brother or my brother to kill me? No, please not. It is not like Sister Williams [Venus and Serena]. Boxing and tennis, completely different.
SI: You and your brother have met many famous people. Who has impressed you most?
Klitschko: I was really impressed from Bill Clinton. We had a conversation with him in Munich. He gave a speech about what is happening in the future, and we later had dinner and conversation. He said, 'Hey, guys, I know who you are. I am a big fan of yours.' I don't know if he was joking, but it was nice to hear it
SI: You led on the scorecards in your title defense against Chris Byrd two years ago before you retired at the end of the ninth round with a torn rotator cuff. That's your only loss. How much does that fight still bother you?
Klitschko: Of course. That fight was broadcast here in United States and everyone saw this fight and I got a really bad critique. Today I can say it was the right decision for myself to stop the fight Because if I don't do it, I think maybe I never have this fight against Lewis.
SI: What did you think of the U.S. as a child in Ukraine?
