One of two season 2 episodes described as "Sunday Specials" (Fantasy Island normally aired Saturdays). These episodes were intended to be "back door" pilots of a Fantasy Island derivative series aimed at children.
Syndicated (Getty/Disney ABC) still-images associated with this episode include several depicting Roarke and Tattoo on horseback in a scene that doesn't appear to relate to the plot (in which Tattoo's screen-time mostly has him the bound victim of a comic kidnap plot).
Juliet Mills (Ruth) starred in "Nanny and the Professor" (1970-71) with Kim Richards whose sister Kyle is in this episode of Fantady Island playing Rebecca. Both Kim and Kyle were child actors in the 1970's and 80's.
