I’ve written about NBC’s Man from Atlantis on many occasions in the past but this just might be my last post about the show for a while. I came across the following information at the Plaid Stallions website. Apparently Kenner, a toy company probably best known for its line of Star Wars action figures, was planning to release action figures based on Man from Atlantis sometime during 1978. You can see a prototype Mr. Schubert figure here, as well as concept art for vehicles and creatures, plus a piece of production material for the Cetacean submarine. Here are pages from a 1978 Kenner catalog that feature a Man From Atlantis dip dots painting design book and a Man from Atlantis see-a-show viewer (a ViewMaster knock-off).
When Man from Atlantis was canceled, rather than scraping the figures entirely, Kenner redesigned them and released them as Scuba Squad, which you can read about here.
