The Westin Bonaventure Hotel and Suites in central Los Angeles is seen under construction outside the window of the motor lodge hotel where Lou Carver (Quinn K. Redeker) and Cleo Donatello (Diana Hyland) have their tryst. Construction began in 1974 and completed after the episode first aired in February1976.
Everytime the camera picks up a clear view of Diana Hyland, guest starring as Cleo Donatello, that includes her left hand, a flesh-toned, square bandage atop the limb is noticeably evident - with no explanation offered. This could be an indication of the chemotherapy treatments she would have been taking to fight her breast cancer. It's that often fatal disease that took her life a year after this show ran.
