It was based on the 1964–1967 CBS television series Gilligan's Island and featured all of the actors from the show, with the exception of Tina Louise, who was determined to distance herself from the role of Ginger Grant (the animated Ginger became a platinum blonde in case Louise objected to Filmation using her image), and Dawn Wells, who was on the road in a play and was unavailable (Jane Webb voiced both Ginger and Mary Ann; she was credited as Jane Edwards for the latter). Added to the cast was a sidekick for Gilligan, Snubby The monkey. Much like other Filmation series at the time, many of the episodes concluded with Skipper and Gilligan talking about whatever lesson they had learned that day.
