I had huge fun with Chris Evans, as Captain America, because super-soldier though he may be, he's still a man, up against a God who in his own mind is infinitely superior. Then, in the ring with The Hulk, we've got this silver tongued, lightening quick mind up against the embodiment of rage..Loki has this mercurial, transformative ability, not just physically but intellectually, so not all the fights are purely physical. Mind games? Maybe.

I’d like to fight everybody who wants to make war on people. I’d like to fight bullies, actually. I’d like to stand up to the bullies in this world. I was actually mugged once in London, and I was completely defenseless. They came at me with a… I was held at knifepoint. And I felt so angry that I let them do it and I think I’d like to go back and say ‘Look, it’s okay’, and if they tried to stab me, I could just say ‘You can stop that now’.

Loki in 'Thor' is the most incredible springboard into a sort of excavation of the darker aspects of human nature. So that was thrilling, coming back knowing that I'd built the boat and now I could set sail into choppier waters.

It was quite a European war until 1917, when the Americans joined up. They don't have the same sense of the loss of innocence and the cataclysmic loss of life. A whole generation was wiped out.

Once you've seen certain things, the moral compunction drives you to act.

Real love is strange and changeable… but also somehow constant.

The weird thing about serious acting is I've always done impressions of people, all my life, and I did the thing called a balloon debate. The idea is there's a hot air balloon traveling across the Atlantic and it's going down and you have to give a speech as to why you should stay in the balloon. Six people are going to be chucked out and you want to stay.
