Filming began on 5 January 2015 and wrapped on 10 February 2015. Moffat confirmed the episode is set in Victorian London saying, "The special is its own thing. We wouldn’t have done the story we’re doing, and the way we’re doing it, if we didn’t have this special. It’s not part of the run of three episodes. So we had this to do it... It’s kind of in its own little bubble."
