The worst job I ever had was as a telemarketer for, oh, I don't know, I think I made it about 90 minutes. I quit before lunch. I went in around 10:30 or 11 and said, 'I can't do this.' It was horrific. I had too many people yell at me within that 90 minutes to be able to continue.

Frankly, as much as I love to improvise, it hasn't been difficult to stick to the script on 'Mad Men.' The writing is so precise, and the story so carefully crafted, that I don't think there's room - or need - for ad libbing. I could never come up with dialogue as lovely as these writers do, anyway.

I was a temp for three years in New York when I was auditioning; when I was cast in 'Mad Men,' I was still a temp. I'm good at making copies; I'm good at typing things. I'm good at killing the day and making it look like I'm doing something.

You make your first album, you make some money, and you feel like you still have to show face, like 'I still go to the projects.' I'm like, why? Your job is to inspire people from your neighborhood to get out. You grew up there. What makes you think it's so cool?

I've never had much interest in spinoffery - the idea of writing in someone else's universe generally leaves me cold - but 'Doctor Who' is different. I've grown up with it. It's been part of my life since I was tiny, watching Jon Pertwee on a grainy black and white television in Cornwall and being terrified out of my mind.
