I had an inspirational teacher at my junior school: Peter Nixon. He was enthusiastic, knowledgeable and slightly scary - a good combination for a teacher.
Dad was a strict disciplinarian and would give us a wallop with a wooden spoon if we were out of order. But we really respected him - he didn't try to be our best friend.
If I wasn't an actor, I'd be a moody folk singer, sitting on stools and being very depressing.
My childhood was very gregarious, and I was usually surrounded by close family.
There's always an anxiety about playing literary characters because one of the great joys of reading books is that you can create your own vision of things.
My mother was gentle and warm. She was the sort of person you could really open up to. I was the eldest and her only boy, so I guess I was treated differently. She did bring me up as a Catholic, and at one time I was an altar boy, but I lost my faith, as did my father, when my mother died at 45.
When I was 13, I won a scholarship to boarding school. My parents let me choose whether to go, and I decided I wanted to. Afterwards, I went to Cambridge to study law - in a way, I was carrying the academic hopes of my family, as Mum and Dad left school at 14.
I'm a massive sucker for music documentaries.
I come from an Irish working-class background but went to a posh school, and any type of pretension was quickly mocked at home. I've always had a keen eye for pretension.
My upbringing is so fundamentally different to my parents'. It must be strange to look at your child who not only speaks with a different accent but has a totally different view of the world.
I spent six years touring the world playing Shakespeare, Molire, Shaw, Goldsmith... But I slowly came to realise that the people you are working with are as important as the parts you play, and that there were lots of interesting people working in film and T.V.
I am a passionate believer that comedy is a way of tackling some of the most dark and difficult aspects of being a human being.
