While the arena shows were at their height, Television Character Promotions ambitiously decided to add another string to their bow, as the May 1976 newsletter proudly announced the forthcoming Planet of the Apes stage play: "At last, the highly successful "Planet of the Apes" comes to the stage. Action, Drama and Excitement. Fun for all the family. 19th July for five weeks. Book now." This original Planet of the Apes theatre script was penned by Fight Director Mike McCarthy, based largely on the pilot episode of the TV series, mixed with elements of Pierre Boulle's novel, the films and an earlier script idea by producer Mike Caulfield.
