One thing House needs Wilson for is vanity. He needs someone to laugh at his jokes.

This was the tricky bit. The really tricky bit, trickiness cubed.

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.

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 remember watching Mel Gibson on some show once, and he was being asked about his belief in the afterlife. Gibson said: 'Well, I can't believe this is all there is'. And I thought: 'Wait a minute. You're Mel Gibson. You have millions of dollars. You're a great-looking chap with every conceivable blessing that could be bestowed upon a man. And that's not good enough ?'
