When this was a two-part episode. the producers did not want a cliff-hanger ending suspended over a week’s time. So, the cliffhanger trap was cut out. But no one caught the plot error that developed. When the duo arrive at the lighthouse the Joker is surprised when Batman, Robin, and Batgirl. He believed they were all dead. When it was decided to cut out the trap, no one apparently caught the error in the Joker’s dialogue.
Yvonne Craig: ‘The production crews on ‘Batman’ were sensational; they all liked one another. We worked very well together. They had worked together for a long time and were held together by the production manager, who was Sam Strangis, who later went on to direct a couple of them and produce other shows at Paramount. If you are a regular in a series, everywhere except Universal, where they change crews on you, you get the same crew every week, so they all get along and work well together and are pulling for the show.”
The guest stars in this episode are mixed bag, Joe E. Ross (Ooh Ooh!) fresh from It's About Time makes a cameo appearance. Ronald Long, as Karnaby Katz, does his trademark Charles Laughton impersonation (he was Admiral Zahrk on the Lost in Space episode Mutiny in Space). Dick Kallman was formally the star of a short lived sitcom called Hank (he was later brutally murdered) was Little Louie Groovy. Louis Quinn as the Lighthouse Keeper was formerly Latch in the Impractical Joker episode last season. Gil Perkins returns as Marvin the Moose (the jury forman) a supposed former Catwoman henchman.
When Ross wrote for Julie Newmar he had a good thing going, but when he wrote for Eartha Kitt, he just lost it. Were it not for his two King Tut episodes this season, his work would be a big let down.
