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.

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.

If you are at a boys' school, especially, there is a level of bravado that you have to keep up otherwise you'll get picked on.

I fundamentally believe that in the moral balance of the human race, we right ourselves. If we feel like the ship's keel is off, we find a way to steer ourselves through the storm repeatedly.

I grew up watching 'Superman.' As a child, when I first learned to dive into a swimming pool, I wasn't diving, I was flying, like Superman. I used to dream of rescuing a girl I had a crush on from a playground bully.

What I learned in Guinea is that we are all responsible for the state of our world. The world - and the system by which we trade, share, cooperate and conflict - is clearly not working. We are only as strong as our weakest members. UNICEF is run at every level by strong, relentlessly energetic, deeply capable people who use that strength, energy and capability to help those who need it most: the weakest, most disadvantaged women and children of our world. All I can do now is help make people aware of what is happening, of what they are doing. That is all that I can do. For now.

Make love, not war. Unless you’re Loki, in which case: do what you want.
