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.

In 'Thor,' that was my own hair. I grew it out. But I have naturally curly, blonde hair, so I'll never look like that. By the time I got to 'The Avengers,' I had come off two other films, which required me to have it very short. So I dyed it again and it was long enough to use a part of my hairline.

When people don't like themselves very much, they have to make up for it. The classic bully was actually a victim first.

Artists instinctively want to reflect humanity, their own and each other's, in all its intermittent virtue and vitality, frailty and fallibility.

Fame is weird and amorphous and unpredictable.

I think the early years, the first decade of your life, is the most formative in a way.

We should just thank each other for our time. For the rest of our lives.
