You are worthy of love and respect. You are beautiful, gifted, and intelligent. Don't let the storm make you forget it.

I love having debates with people when they are debates but some people, you just can't. Some people shouldn't be given the oxygen.

Maybe that's when bad scripts are written, when you choose the theme first. I consider that I've something to say when I've thought of a person, a moment, a single beat of the heart, that I think is true and interesting, and therefore should be seen.

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.

In the end I sort of though we created a companion who was so alive and dynamic and so wedded to the doctor that you’d need a whole universe to contain her in.

I dread the day I leave [Doctor Who], because then I'll have to go back to writing bedrooms and offices and pubs. And maybe a field, if I'm lucky.

Rose Tyler: Can't you come through properly? The Doctor: Then the whole thing would fracture. The two universes would collapse. Rose Tyler: So?
