I drink booze, I smoke, and I'm hooked on caffeine. I actually have been known to swear at times and belch and even raise my voice when provoked. And I'm not physically repressed!

Journalists are always calling my features Edwardian or Victorian, whatever that means. I am small, and people were smaller in those times. I'm pale and sickly-looking. I look fragile-like a doll. But sometimes I just wish I had less of a particular look, one that was more versatile.

People have lots of misconceptions about me. My mum, who is half French and half Spanish, gets outraged when I'm called quintessentially English. I owe my looks to my mum-which was 90 percent of getting my first job. And, some people would argue, 90 percent of my entire career.

I don't think any actor wants their children to follow them into the profession.

It's impossible, I think, however much I'd become disillusioned politically or evolve into a post-political person, I don't think I'd ever change my view that socialism is the best political moment humans have ever come up with.

David Holdaway was my stage name. I was an actor for about eight years in the '90s. I had to change my name because there was another David Nicholls, and I thought if I changed it to my mother's name, she'd be touched.

I found my sound early on. Look at U2: they haven't changed their music for 20 years. Anyway, many people come unstuck when they try to change what they do and what they are known for.

The process of my transformation came to a head with my discovery of St. Francis of Assisi during a pilgrimage I went on with a scout troop from my school.
