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.

Within us there is the capacity of being anyone or anything

I think we all see ourselves as the heroes in our own lives.

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

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 thought theater people wouldn't see me if I hadn't trained. I didn't want to just be the Brideshead guy, to spend the rest of my life wearing waistcoats. I got the chance to try everything.

What le Carré is so good at is unpicking something very specific about Englishness. That is almost part of why I think he wrote the novel. You can feel le Carré's anger that someone who has had the benefits of an English education and an English upbringing is using that privilege to basically do the worst things imaginable. There is an anger in the book about that.
