Executive Producer Caroline Skinner on being asked if all the scripts had been written.
"No, if only. But we’ve got a lot of them and the ones that are written are really, really epic and very exciting. (The opening episode) is indeed written by Steven and it’s going to blow everybody’s mind."
BBC Controller Danny Cohen said this on Richard Bacon's Radio show.
"The Doctor Who team are writing away. There are more episodes next year. We've got some big events coming up in the near future. So, stay tuned! I always try and keep things close to my chest with Doctor Who because there's such interest in it, and I think it's right that Steven Moffat and the team are the people that bring the news on Doctor Who to the audience rather than me."
Writer Toby Whithouse had this to say about his episode.
"My episode is in a genre I’ve never written before — frankly, no one has written in that genre for quite a while now. But I absolutely love it. Steven gives me a one-line pitch, and then I’ll go away and put together a story and so on. And he gave me a great one-line pitch for this, so I’m really excited about it.
Doctor Who is always a joy to write. It never gets boring, it never gets dull, it never gets routine. It’s an incredibly difficult show to write because it’s remarkably complex, but it also has to have such momentum and pace. And within that there has to be room for character and humour and so on. It’s always a huge challenge but always extraordinary fun. That’s why I keep going back."
