The 11 minutes interview with Steven Moffat is from 2013, but it was uploaded on Youtube only last month by the BBC Writer’s Room. The executive producer and head writer of Doctor Who and co-creator and executive producer of Sherlock talks about how, where, when, what and why he writes. With some interesting details.
Notable points of interest include: he has a Weeping Angel in his garden, he’s a terrific fan of TV comedy, he can’t sing, Doctor Who’s “Blink” and Sherlock’s “A Scandal In Belgravia” were both shot in the same house.
