Clearly, there's a real onus on you to do something correctly when everybody, at least in the United States, had a really clear, specific idea of what this guy looked like - and even more so, what he looked like as Clark Kent and as Superman. You have this whole vast audience of people who would be acutely aware of any deviation whatsoever and probably holding you to a slightly higher standard as a result.

One of the differences between now and then is that the idea of body image is a much bigger issue now. Back then, just being kind of heavy and barrel-chested passed for heroic. Now, you wouldn't dare to play a hero without a lot of dieting and various specialised abdomen machines. But that was one of the things which was interesting about it and I did want to portray because there's good and bad.

When you are in your 20s and you're not married with kids, you're having fun. But when you're in your 30s and you're not married and don't have kids, you begin to develop a Peter Pan complex. As you grow older, you have more responsibilities and you have to step up to them.

I've seen high and lows. When things go well that doesn't make me feel like some genius. Nor will I allow the next disappointment to make me feel like a complete failure.

I've never held myself up particularly high when I had movies that worked, and I never held myself all that low when I had failures.

They say money can't buy happiness? Look at the smile on my face. Ear to ear, baby!

You have to be kind to people. Treat them decently. There's no excuse for not.
