"[Mark Gatiss and I] are very, very old friends, so we’re having about as much fun as we could ever imagine having! I remember once, back in [BBC Wales studio] Upper Boat, you had the TARDIS in one studio and the next studio was 221b Baker Street. Mark grabbed my arm and said, ‘It’s like a map of our brains!’"

— Steven Moffat (x)
