Moffat has been an executive producer and a lead writer on both shows since 2009.

Speaking to French websites including Reviewer.fr and Le Village, the writer commented: “I don’t know how it fits. We had a scheduling meeting last night which was the most depressing thing I’ve ever seen. We never had a scheduling meeting for the first two years of Sherlock and Doctor Who, which was a much better idea because… you would see that it doesn’t fit; it can’t fit!”

Moffat continued: “At some point you’re going to have to write a script really fast. In a turf war you never want to be the turf, I’ll tell you that! I sat and drank a whole bottle of wine, because you can’t plan these things. There’s no way it works – except it does, somehow, somehow you get there!”

Series 7 of Doctor Who began filmin last month and a transmission date and filming details for Series 3 of Sherlock have not yet been announced.
