The Doctor: Rose... before I go, I just want to tell you: you were fantastic. Absolutely fantastic. And do you know what? [Pause] So was I!

Rose:i love you Doctor:Quite right, and i guess if it's my last chance to say it... Rose Tyler... (the doctor fades, him in his TARDIS, with tear tracks and a tear running down his cheek)

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. The only way to get rid of her is to send her into a parallel world from which she can never return; otherwise she would stay with the doctor forever.

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.

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.

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.
