I always found the extraordinary loss of life in the First World War very moving. I remember learning about it as a very young child, as an eight- or nine-year-old, asking my teachers what poppies were for. Every year the teachers would suddenly wear these red paper flowers in their lapels, and I would say 'What does that mean?'

I love playing all kinds of roles. I hope it doesn’t sound too pretentious, but I always feel human nature is like a piano, and there are 88 keys, and there are some white keys and some black keys, and each character is a different chord on the piano. Basically, I hope that in the course of my life, I will have played all 88 keys. So, I’ll have played heroes and villains and princes and kings and warriors and beggars and thieves and lovers and fathers and wizards and all of those things. That is why I’m an actor… I love studying people.

We pull on to the road, where our only company are the wandering cattle, who have become commonplace as traffic lights. Lethargic and listless, they look like they've been roaming the roads of Guinea since the dawn of time. And no doubt they will continue to long after we're gone.

I am desperate to do a comedy now.

I loved adventure movies. I loved movies where people went on an adventure to an unknown land, an undiscovered country, or a new territory. I think there's something, right at the center of storytelling, that people love about that.

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.

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
