I think the fact that us as a race still continues to be very tribal and we haven't really moved away from that over hundreds and hundreds of years of experience.

I suppose the doctor-patient relationship has that idea of transference. I think it's a special thing that doctors have. We all find doctors sexy. That's why there are so many TV shows about doctors.

There's no point thinking, 'Well, my life's certainly worked out, I've got all the answers.' It would be wrong for me to say that I don't get seduced by certain things. That things don't become tempting.

For me, addiction comes down to basically where a pattern of behaviour has developed and that pattern of behaviour is becoming a very damaging cycle. It's sort of damaging your relationships, friends or lovers, it's damaging your own personal health and it's damaging for you and your workplace.

People are complicated. Our behavior towards one another is strange. So I like opportunities to investigate that.

Why not provoke some thought and get people talking about things? I like characters that are flawed because we all are. When people break up in a script, you think, Oh, right, there must be tears shed here. But maybe the fact of the matter is that they're both laughing.

Nobody wants to hear Metallica at lunchtime.
