The couple who play Julie and Richard Dunn were also married in real life.
The non-transmitted pilot "People Together", and episodes Episode #1.22 (1980) and Episode #2.10 (1981) are missing from the archives.
Unusually for a TV drama of this period, series 2 was broadcast live, meaning that topical news and current events of the day could be mentioned in the script.
Minus the pilot and episodes 1:22 and 2:10 which are missing from the archives, the series was released in a 6 disc DVD set in 2020 by Renown Productions. All episodes are full and complete with no cuts.
