I once sang 'Summer Nights,' from 'Grease,' at a bar in Melbourne with John Travolta, who's a good friend of mine. He looked cool singing the part of Danny - sitting in an armchair, smoking a cigar - while I got stuck playing Sandy.

For me that's one of the great indulgences in life - a hand-tailored suit, and a great pair of handmade shoes.

It's fair to say that, by 'X-Men 3,' Wolverine had gone a little soft, and I agree with them there. What fans love about Wolverine is his more uncompromising approach to life. He is who he is. He's not always a nice guy. He has got edge. He's an anti-hero. And, there's also a vulnerability in there. There is conflict and battles going on in there.

If I weren’t getting paid or didn’t have a character like Wolverine to maintain, I would just be a tall, lean, fit guy.

I'm a big goofball, you know. Don't tell anyone that, but I'm a big goofball. In Australia we call it a dag.

Sometimes you have to go places with characters and emotions within yourself you don't want to do, but you have a duty to the story and as a storyteller to do it.

I would love to have a robot at home.
