I was so lucky because what I did in 'Thor' was I built the character from the ground up - the foundations of his spirit, really. He was someone who was born with an expectation that he would one day be a king, born with an entitlement.

It’s always about, somehow, finding a part of myself that is relevant, and then turning the volume up on that particular part. So, I am all of the characters I've ever played, and I am none of them at the same time.
