One of the great flaws that we all share is that we think everyone else is cooler, everyone else is sexier; everyone else has all the answers. That was me too.

It's like playing tennis, you play a different rally with different people. Every actor is different and the chemistry between actors is different.

What is the best use of my time on this planet?

Never stop. Never stop fighting. Never stop dreaming. And don’t be afraid of wearing your heart on your sleeve - in declaring the films that you love, the films that you want to make, the life that you’ve had, and the lives you can help reflect in cinema. For myself, for a long time… maybe I felt inauthentic or something, I felt like my voice wasn’t worth hearing, and I think everyone’s voice is worth hearing. So if you’ve got something to say, say it from the rooftops.

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’m not a big fan of the class system, to be honest. It feels ugly to me. If you’ve got something to say and the work is good, it doesn’t matter where you come from

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.
