I read mostly historical fiction - lots of stuff set in ancient Rome and ancient Greece. I also liked sci-fi and fantasy: David Gemmell, Raymond E. Feist. It's a nice escape from the world. As much as I do love real-life stories, they can often make you hurt in a way I'd rather not hurt.
A large amount of constant activity will get things going. For example, training in the morning will have everything, all the juices flowing by the time you actually get to work. So, when you're at work, you've been already up for an hour or so or two hours, and you're raring to go where everyone else is still wiping sleep out of their eyes.
A lot of the stuff you do as an actor - or I do, because I can't speak for everyone - is not always consciously thought out. A lot of the time, for me, it's actually just feeling stuff, and it happens all in the moment and your body reacts.
Certainly, for younger guys, Superman is this mythological character that they've thought about and explored in their imaginations... But one thing I really like about Superman fans is that they're so open-minded and excited and honest. There's something beautiful about their enjoyment of it - something very Superman-like.
I found very interesting - trying to separate the different facets of Superman in that way. When you're aware of how people perceive you, you can't always remain true to yourself, and that was an interesting thing for me to apply to the character as well - exploring these different facets of his personality while having certain bits of it stripped away. The arrogance of a person who would have the kind of power that Superman does - we see that in The Return of Superman. Superman is not that character, but since he has all of those powers, he has that capacity for arrogance.
I often find during a day of shooting I will speak in an American accent all day long when I'm doing dialogue. At the end of the day, it often takes an effort when I'm talking to my fiancee to bring my English back just because you're so used to speaking that way.
