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.

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.

The 60s had completely changed how people conceived of their lives and their habits and their identities.

My father and I used to tussle about me becoming an actor. He's from strong, Presbyterian Scottish working-class stock, and he used to sit me down and say, 'You know, 99 percent of actors are out of work. You've been educated, so why do you want to spend your life pretending to be someone else when you could be your own man?'

I am no saviour. I’m absolutely the last person on the planet who can practically help. I don’t know how to make the different types of therapeutic feeding milk. I’m no chemist. I’m no doctor. I’m no engineer. I can’t manufacture polio vaccines or organise their transportation to the health centres in Saramoussayah or Bissikirima. I can’t build schools, or design drainage systems. I can’t provide the women and children of Mandiana with water.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.

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.

If you can run around the corner and say hello to someone do that instead of emailing. It's always more rewarding; the connection is always more authentic. If you've got something to say and you can say it someone's face, it's so much better, healthier.
