Although this episode is presumed to take place in the "present" (early 1975), the calendar behind the desk clerk of the Dolphin Motel clearly states January 1972. Later in the episode at Maggie Larkin's place, there is a calendar on the wall showing the month of August. Although no year is clearly visible, the days also correspond to the year 1972. The company distributing this calendar is named "Brown & Bigelow." The two main characters in this episode are named Bigelow although no firm with that name is mentioned or implied. Coincidence?
Tom Selleck makes a brief appearance in this episode. Four and a half years later (1979) actress Erica Hagen (Maggie Larkin) appeared on The Rockford Files in an episode ("Nice Guys Finish Dead") guest starring Tom Selleck, this time appearing in a scene with him.
