Life is generally pretty damn amazing if you let it be.

Chris Hemsworth is like Christopher Reeve in that he can do two things: he can wear a big red cape without a shred of self-consciousness. But he's also funny as hell, and he's so sweet. So with all the fish-out-of-water stuff, he's so funny. So he does almost two jobs in a way.

I love playing all kinds of roles. I hope it doesn’t sound too pretentious, but I always feel human nature is like a piano, and there are 88 keys, and there are some white keys and some black keys, and each character is a different chord on the piano. Basically, I hope that in the course of my life, I will have played all 88 keys. So, I’ll have played heroes and villains and princes and kings and warriors and beggars and thieves and lovers and fathers and wizards and all of those things. That is why I’m an actor… I love studying people.

Joanna points her camera at a section of society unused to having cameras pointed at it. But I don't know about categorising them in terms of class; I'm a bit wary of that. My dad is the son of a shipbuilder.

If you are at a boys' school, especially, there is a level of bravado that you have to keep up otherwise you'll get picked on.

If you play it straight it's funny - the best comedy is always played straight down the middle. The adjustment is understanding from the screenplay that a moment is hilarious.

I would always play the baddie, incidentally.
