This is Jack Grinnage's last appearance as recurring character Ron Updyke. Although Grinnage was contracted for every episode of the series, he was released because he had an appearance scheduled in a pilot filming elsewhere, and the producers had been informed by ABC that this series was canceled. (From Mark Dawidziak's 'The Night Stalker Companion.)
Jack Grinnage's character, Ron Updike, states that with proper diet and exercise, a person could live to be 90 years old. Interestingly, Jack Grinnage was the last surviving member of the cast, having lived to over 90 years of age.
