The Castaways on Gilligan's Island

A sequel to Rescue from Gilligan's Island, The Castaways of Gilligan's Island is a movie that folowed up the series and movie and was intended to be a potential pilot to a new series. Having returned to The Island, the Castaways are rescued once again as Mr. Howell follows up with his plans to turn the island into a resort.

Synopsis
Once again stranded on the same island, the Castaways learn from the Professor that the storm that washed them off the island to their rescue the year before has contaminated all of the underground freshwater springs on the island. While exploring, however, Gilligan also discovers that the storm has uncovered and exposed an old abandoned Air Force hangar with planes once hidden from virew by underbrush. The Professor believes that he can repair at least one of the planes with parts from the other to fly them all back home, creating a Frankenstein-like craft they dub the Minnow 3. Unfortunately, the unwieldy craft does not perform as expected and they have to jettison their supplies, Gilligan tumbling out with them. The Skipper requests they turn back to search for Gilligan's parachute, and almost right after landing, one engine then another falls off. Although they are still back to marooned on the island, they all realize going back to get Gilligan saved them from plummeting to their deaths. Shortly after finding Gilligan hanging in a tree, Navy officers arrive looking for the plane that appearead and vanished from radar, recuing the castaways once more! Over the following year, Mr. Howell converts the island into a fully-functioning tropical resort linked to civilization and with Gilligan, the Skipper and the others as silent partners in the hotel. They now live again on the island with all the comforts of civilization and a link to the main land. With the Howells as hosts, Gilligan and the Skipper escort and bring in guests, Ginger and Mary Ann cater to the female guests, and the Professor conducts personal experiments between tours of the island. Among the guests, Gilligan notices a young boy running loose without his parents, and the Skipper and Mr. Howell meet and deal with a workaholic named Henry Elliot unable to relax and forget about work. Gilligan tries to help the boy make peace with his parents pressuring him into academic pursuits as Mr. Elliot learns to relax and trust his employees back home.

Trivia

 * The Professor must have taken flight training his year off the island or become presumptuous of his flying ability because in Wrongway Feldman he previously revealed he wasn't able to fly a plane.
