I love Prince Harry. Good looking and a bit of a rebel. Me and his dad are as thick as thieves and I knew Harry before I knew his dad so we've met a few times. I think he's amazing. And I think you can relate to him because he's made mistakes. He's cool.

We all have roles in life. I'm a dad, a husband, this and that, but basically I only feel justified in being alive when I'm on the stage.

I have a weird sense of humour. My dad's the same. We love watching 'Monty Python' together.

My grandmother was an actress too. In the thirties and forties she was under contract with Universal Studios. Crazy credits, lots of them. My dad was also under contract with Universal Studios. And my first film was shot on the same stage they both worked on at Universal.

I got stuck up a tree when I was about seven, and my dad had to come and get the ladder to get me down. I loved to climb all the way up to the top. I must have been a koala in my past life.

No, like I said, my dad was never really part of the tennis. His involvement around what I did with the tennis and with my mom and my grandparents was really not a part of my life.

I've hung out at dozens of playgrounds, bored out of my mind, with not even a look of comfort from disapproving mothers all around me. Either they think I'm a pedophile or a deadbeat dad. That's what I get for being a single dad - suspicious looks at the playground.

My mum's parents were from Ireland, my dad's mum was American-Irish.

Obviously, losing a parent is very difficult. I miss my dad every day, but I know he would be proud to see me continuing to swim and going for another shot at the Olympics.

I actually study boxing - my dad was a Golden Gloves champion so I learned how to fight at a very young age. Growing up in Brooklyn you always had to watch your back, so I pretty much learned to protect myself.
