Mike Stephens is listed, along with Harold Snoad, as "film sequences directed by". This is due to the fact that some of the footage Stephens directed for Unbroadcast Pilot (1986) was reused for this episode.
However, Stephens also directed a studio sequence recorded on video, for which he isn't credited: the scene where Maisie calls on Rita in her flat was also reused material from the pilot.
