Synopsis by Hal Erickson
Dr. Scorpion (Roscoe Lee Browne) is a megalomaniac genius, who plans to rule the world with or without the world's cooperation. His chief nemesis is marine biologist Jonathan Shackleford (Nick Mancuso), an ex-spy better known as "Shack". Shack was also the title of the TV series for which the filmed-in-Hawaii Dr. Scorpion was the pilot. Producer Stephen Cannell lost interest in the project almost from the beginning, thanks to the network-imposed casting of the Nick Mancuso in the leading role (Mancuso agreed that he was wrong for the part, but a buck's a buck). Still, the notion of a Hawaii-based spy appealed to Cannell, so much so that he later revitalized the notion as the moderately successful TV series Stingray.
