This was Joe Flynn's last professional film performance on television or movies. After this episode aired (December 11th, 1973) he kept busy as a panelist on the popular television game show Match Game '73 and Match Game '74. Previously, Flynn was best remembered as Captain Binghamton in the 60's sitcom McHale's Navy. Before that, Joe was a ventriloquist who had served in the Army stateside entertaining the enlisted men. He also appeared on Batman, although in the second season and thus did not work with Yvonne Craig (Batgirl), who also appears in this episode.
