I wish I hadn't worked so hard; I wish I'd had the courage to live a life true to myself, not the life others expected of me; I wish I'd had the courage to express my feelings; I wish I had stayed in touch with my friends; and I wish I had let myself be happier. It's an extraordinary list of getting in your own way, isn't it?

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

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.

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

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.

Artists instinctively want to reflect humanity, their own and each other's, in all its intermittent virtue and vitality, frailty and fallibility.
