I definitely go through periods where I'm in a particular mood, or there's a consistent imaginative context that I feel I'm in, and I'm drawn to certain things. I can sometimes feel it when I'm moving away from something that I was once interested in - an idea or an exploration of particular relationships. I go, 'Well, I think I've done that and I don't want to do it again.'

It is always so alive because he is, essentially, a spy.

If the Loki in 'Thor' was about a spiritual confusion - 'Who am I? How do I belong in this world?' - the Loki in 'Avengers' is, 'I know exactly who I am, and I'm going to make this world belong to me.'

I wish we could be decent to each other.
