It's like playing tennis, you play a different rally with different people. Every actor is different and the chemistry between actors is different.

I try not to make plans. God always laughs at your plans.

For the first 10 minutes after you meet them, they have the wattage and charisma of movie stars. Then you have a coffee with them and you realize we're all the same, we're all just people. All of the actors in The Avengers are so nice. Marvel has these code names for projects and the code name for The Avengers was Group Hug. It felt very much like a group hug on set.

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

I did a production of 'Journey's End,' an RC Sherriff play about World War I, at the Edinburgh Festival. I was 18 and it was the first time that people I knew and loved and respected came up to me after the show and said, 'You know, you could really do this if you wanted to.'

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 believe in the strength and intelligence and sensitivity of women. My mother, my sisters [they] are strong. My mum is a strong woman and I love her for it.
