I didn't realize House would be the central character, more the bitter comic relief appearing occasionally. I relish his wounded nature - the lameness, the scarred Byronic hero.

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

I couldn't imagine what Fox thought they were doing, contemplating such a jagged protagonist for a prime-time drama. I only knew that I wanted the role very much.

I was shown into a room. A red room. Red wallpaper, red curtains, red carpet. They said it was a sitting-room, but I don’t know why they’d decided to confine its purpose just to sitting. Obviously, sitting was one of the things you could do in a room this size; but you could also stage operas, hold cycling races, and have an absolutely cracking game of frisbee, all at the same time, without having to move any of the furniture. It could rain in a room this big.

I just read an 800-page history of the Scottish Enlightenment and, honestly, I may as well just start it again now, because I cannot remember a single thing. I can barely remember where Scotland is.

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.

People are more open about seeking help these days. They recognise the fact that the alternative to having a shrink is that you bore your friends stupid. So I figured that I might as well give someone 100 bucks an hour to hear my woes. At least someone can make a living out of listening to my tedious problems.
