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.
Like the original series and most Saturday morning animated series of the era, The New Adventures of Gilligan contained an adult laugh track.
The show debuted on ABC Saturday morning on September 7, 1974. After 24 episodes over two seasons, ABC relegated the show to Sunday mornings for a third and final season of repeats in 1976–77, as the network, still reeling from the ratings disaster in 1975–76 which was Uncle Croc's Block, was reluctant to order another season of animated Gilligan installments or anything new from Filmation Associates.
Another Gilligan's Island-based Filmation animated series called Gilligan's Planet was made in 1982. The premise for that series centers around the castaways creating a spaceship and winding up on a deserted planet
