I feel like I'm working on an oil rig right now. I'm away from home a lot.

I never went to drama school, I don't have any certificates saying: 'He's a qualified actor.' But I did think that House was something I didn't have to apologise for. It was something I was really proud of and it was sort of ... whether you liked it or not, it was undeniable.

Celebrity is absolutely preposterous. Entertainment seems to be inflating. It used to be the punctuation to your life, a film or a novel or a play, a way of celebrating a good week or month. Now it feels as if it's all punctuation.

As a real person, he wouldn't last a minute, would he? But drama is about imperfection. And we've moved away from the aspirational hero. We got tired of it, it was dull. If I was House's friend, I would hate it. How he so resolutely refuses to be happy or take the kind-hearted road. But we don't always like morally good people, do we?

It's a basic truth of the human condition that everybody lies. The only variable is about what.

Acting is largely about putting on masks, and music is about removing them.

Believe it or not, perhaps I don't show it much, or well, but I think I like people.
