The Harts pet dog, Freeway, (whose real name was "Charlie"), appears in a sequence near the end of the program in which he leads a pony by the rope because he has made friends with him and wants to take him home on the Harts' private jet. Freeway's then 38-year-old trainer Paul Calabria worked with him on the horse trick for two days. The scene was shot on Friday, January 23, 1981, which also marked the last day of filming.
The aircraft they arrived in was an 8 seat Piper Navajo PA-31P. Registration number N95RS.
