Jessica Tandy's husband, Hume Cronyn, starred in the next episode, The Impromptu Murder.
Through the second half of the episode Jessica Tandy's character is chauffeured around Hong Kong. This foreshadows her historic Oscar win at the 1990 Academy Awards when Tandy became the oldest ever recipient of the statuette playing a character who was chauffeured around Atlanta in 'Driving Miss Daisy'.
