I had a bad back for a couple of years. I had to do a lot of physiotherapy for it. What I couldn't understand at the time was why the therapists had me doing a lot of stomach work.

When I made 'Real Steel,' the director actually had the robots in the monitor, so he knew where everything was. So technically, there's been advancements. But at the end of the day, movies are about story and characters, so all the other stuff is great, but unless you have those two elements, then you've got nothing.

Tiramisu is my favourite.

It dawned on me that acting was what I wanted to do with my life. Nothing had ever touched my heart like acting did.

What I respect as far as in myself and in others is the spirit of just doing it. For better or worse, it may work and it may not, but I'm going to go for it. Ultimately I probably prefer to be respected for that than whether it works out or not, either winning or losing.

Now I meet people with full-color Wolverine tattoos on their backs. Thank God I did okay, because I think if I hadn't, they'd spit on me in the street.

My friends say, 'Man you're going to have kids sleeping on pillowcases with your face on it! You're going to be on toothbrushes and magnets and stuff.' I guess now that I'm a dad, I'm thrilled about that.
