Rita Moreno won a 1978 Emmy® award for Outstanding Lead Actress for her work in this episode.
Rita Moreno, who portrays a prostitute on this show, appeared as a stripper in the James Garner film Marlowe (1969).
The car Rita gives Jim at the end is a Gazelle, one of several "kit" cars based on VW Beetles that were made as replicas of classic cars; in this case, a 1929 Mercedes SSK. As with the Bug, the engine was in back. The tail lights are even the same as the Bug.
Both Pat Finley and David Lewis were in The Case of the Skeleton's Closet (1963), which was Ms. Finley's on-screen debut.
Rockford's remark about Rocky being "Just about 98% mother hen" had been previously spoken by Leslie Hartman, referring to his wife, on season three's New Life, Old Dragons (1977).
