Drama's not safe and it's not pretty and it's not kind. People expect the basic template of television drama where there might be naughty villains, but everyone ends up having a nice cup of tea. You've got to do big moral choices and show the terrible things people do in terrible situations. Drama is failing if it doesn't do that.

Daleks: [simultaneously] Exterminate! Exterminate! [They fire their weapons, none of which so much as touch the Doctor] The Doctor: Is that it? Useless! Nul points! [to Rose and Jack] It's all right, you can come out; that forcefield can hold back anything! Jack Harkness: Almost anything. [pause] The Doctor: Yes, but I wasn't going to tell them that. Thanks.

Harriet Jones: Did you notice when they fart, if you'll pardon the word, it doesn't just smell like a fart, if you'll pardon the word, it's something else. What is it? It's more like, um... Rose Tyler: Bad breath. Harriet Jones: That's it! The Doctor: Calcium decay. Now that Narrows it down!.. Calcium phosphate. Organic calcium. Living calcium. Creatures made out of living calcium. What else - what else? Hyphenated surnames. Yes! That narrows it down to one planet! Raxacoricofallapatorius! Mickey Smith: [sarcastically] Oh yeah, great! We can write 'em a letter.

It's tough and it should be tough - it should never be easy to be given millions of pounds to make a drama. The coalition government is doing terrible things to the BBC, but drama will survive even if we end up putting on a play in a backroom of a pub.

There's one tiny little gap in the universe left, just about to close. And it takes a lot of power to send this projection. I'm in orbit around a supernova. I'm burning up a sun just to say good bye.

Rose: My mum's here. The Doctor: Oh, that's just what I need! Don't you dare make this place domestic! Mickey Smith: You ruined my life, Doctor. [the Doctor turns and looks at him, irritated] They thought she was dead, I was a murder suspect because of you! The Doctor: [looks at Rose] See what I mean? Domestic! Mickey: I bet you don't even remember my name! The Doctor: Ricky. Mickey: It's Mickey! The Doctor: No, it's Ricky. Mickey: I think I know my own name! The Doctor: You think you know your own name? How stupid are you?

You’re far more likely to see a naked woman than a naked man. It’s only [seen as] rude because the rest of television is rather tame – it doesn’t actually talk about sex and our bodies and how we feel about them. I’m not out to shock.
