* CharacterOutlivesActor: Creator/JoanSims (Madge) passed away before the final series was filmed. She was written out as being away on an expedition Rocky was uninterested in, and she simply wasn't mentioned in the Reunion Special.
* RealSongThemeTune: "As Time Goes By", as sung by Joe Fagin.
* TheOtherDarrin:
** Lionel’s secretary Daisy was played by Justine Francine Glenton in one episode of Series 3 and by Zoe Hilson in four episodes of Series 4.
** Sally’s eventual husband Harry was played by David Michaels from Series 6 to Series 9 and by Daniel Ryan in the 2005 Reunion Special.
* WhatCouldHaveBeen: The role of Jean was originally written for Creator/JeanSimmons, but she turned it down due to her reluctance to uproot her life—specifically mentioning her dogs, garden, and family—in California.
* WorkingTitle: ''Winter with Flowers''. This was changed when the cast disliked it.
