“I often find during a day of shooting I will speak in an American accent all day…” — Henry Cavill

I'm from a family of six men, so I'm bound to be physical.

I will say I was a lot bigger as Superman. A lot bigger. I'm not saying how much. It's modesty about the weight - I've always been worried about my weight - but I also don't want to invite that debate: 'Henry weighs this, so he's the perfect Superman.' Or, 'Henry doesn't weigh this, and therefore he's not believable in the role.'

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.
