Nature is a definite thing. But nurture is just as powerful. It can really mess with you.

I know there are a lot of people who like to get very involved in their characters, but I, personally, find it too involved. I just like to do it as a job - and it's my job to make it look real.

I work out two, two and a half hours a day.

Playing an icon [superman], you don't try to be an icon because that defeats the purpose. The responsibility attached is enormous, and the realization that it actually really, really matters meant that I wanted to put the most amount of work into representing the character properly.

Everyone doubts themselves. It's just a matter of admitting it or not.

Whether someone else would have played Superman better or worse would be up for a lot of debate on the internet forums, I'm sure.

You can train and train until you are blue in the face, but you've got to diet, you've got to have that leanness because if you are not lean, your abs won't show. Of course, the training has to be put in, but then you've to shed all the fat and keep the fat off. And that's how you get an eight pack.
