First credited appearance in TV or film for James Cromwell. He plays the Countess' tennis instructor, Terry.
About 40 minutes [ @43:00? ] into this episode, there is an exterior shot of a house, presumably the Countess's house. This same house was used to depict the exterior of Jonathan and Jennifer Hart's house in the TV series "Hart to Hart."
Although not credited in the original teleplay, Leah Richards is played by Gloria Dixon.
The Countess' sports car seen parked by Jim's trailer is a (Ferrari) Dino 246. Although built by Ferrari, the company did not consider them true Ferraris since they had V-8 engines instead of the customary V-12s. Many buyers bought their own Ferrari badges and put them on themselves.
No acting credit for the actress playing the role of character "Leah Richards."
