Produced by the Filmation studio Gilligan’s Planet was another spin-off of the show Gilligan’s Island which aired from 1982 to 1983. The show was short lived as only 12 episodes were made during that time frame.
There was originally two animated television series based off the original television series with this being the second, the first show running in the early 1970’s was called The New Adventures of Gilligan.
The show was based around the original group of characters and a Professor who built a spaceship, this was in order to get the castaways off the island.
What I don’t understand is that they could simply just repair the hole in the ship but instead they go to space as the rocked sored off and managed to crash on an unknown planet.
