• Underage Casting: Gillian Barge, playing Mrs. Inglethorp (a character in her seventies), was, at fifty, only eight years older than David Rintoul, playing her eldest son, and two years older than Michael Cronin, playing Alfred Inglethorp, whom being twenty years his wife's junior is a plot point.
