I was too shy, I think, to sing publicly. It takes a particular kind of person. And when I was young, I was not that person. In the first instance, when a record company said to me, do you want to try and make your record, my first reaction was, no, I'm not worthy - I couldn't possibly, and so on and so forth.

I think maybe even one of the reasons I became an actor was actually to hide. I mean, it sounds paradoxical because, of course, people are standing up in a public place and encouraging other people to look at them. So that's not the conventional definition of hiding.

I don't think of myself as funny. I think of myself as rather grave, actually. And I'm suspicious of fun. I never quite know what that is or how to deal with it or how to generate it. That's my fault. I know it's a burden on the people I'm with. It's tiresome.

I think good-looking people seldom make good television. And American television studios almost concede before they start: 'Well, it won't be good, but at least it'll be good-looking. We'll have nice-looking girls in tight shirts with F.B.I. badges and fit-looking guys with lots of hair gel vaulting over things.'

When I was a small boy, 10, 11, 12, probably somewhere around there, when I first heard a blues song on the radio, it was a jolt of electricity. It grabbed me by the throat, it made me shiver. And I knew from that moment that this was for me and this would be with me for the rest of my life.

I feel when acting, I am sometimes overly self-conscious; I think, 'Going, no, don't, put your eyebrow back where it was and, you know, turn to the left.' You know, I'm sort of very consciously adopting this character. But with music, I don't know. I found it was a question of just closing my eyes and just sort of letting things come out.

Directing is the best job going. I don't understand why everybody doesn't want to direct. It's an absolutely fascinating combination of skills required and puzzles set on every level - emotional and practical and technical. It calls up on such a wide variety of skills. I find it completely absorbing. I just love the whole process.

I think my father gave me a great reverence for medical science. He was about as opposite to the personality of House as one could imagine. He was polite and easygoing, and would have gone to great lengths to make his patients feel attended to and heard and sympathized with.

Lots of people would say House doesn't have any charm at all. I would disagree, though: I find him immensely charming and endlessly entertaining. He has a sort of grace and a wit about him, and ultimately, I think he is on the side of the angels.
