Speaking to Ed Stradling at the Gallifrey 2013 convention in Los Angeles on Sunday, Moffat revealed: “[We’ve got] a lot of different things going on. Don’t believe the nonsense about one 60-minute film, that is complete nonsense. We’ve got a lot of things coming up for that. It’s hugely exciting.”

Discussing the difficulties of shooting the 50th anniversary special in 3D, the writer commented: “I think it poses every kind of logistical problem! You can imagine it takes much longer to shoot. Every CGI shot has to be done twice. It’s a proper old headache. But wouldn’t it be kind of awful if some other show was the first one to be 3D? It has to Doctor Who, hasn’t it?”

Series 7 Part 2 begins on Saturday 30 March on BBC One and BBC America.
