I'm grateful for people who have believed in me when others might not have.

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.

The language of digital communication is a language we don't understand in a way. People say the internet is like the Wild West in that it's lawless and we haven't worked out how to make it structured or moral.

I even feel grateful for the failures.

My instinct is to keep people guessing. I think as an actor your greatest strength is your versatility, I suppose. The blanker the canvas, the easier it is to project the illusion of a character onto it. I think there are many actors who do that very successfully.

You've got to do something, even if it's just to kick-start the day. I use music. And running.

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?'
