Gilligan's Island is an American TV sitcom originally produced by United Artists Television. It aired for three seasons on the CBS network from September 26, 1964 to September 4, 1967.
The Harlem Globetrotters crashland on the island. When a millionaire tries to take over the resort, the rivalry is settled by a game between the Globetrotters and the rival's robot team. Jim Backus (Thurston Howell) has only a walk-on part at the end of the film as he was suffering the advanced stages of Parkinson's disease by then. His role on the island was filled by creating "Thurston Howell IV", played by David Ruprecht, the couple's supposed son. (Conflict with the first season episode in which Gilligan was adopted by the Howells after saving Lovey's life. He was said at that time to be their only son.) Constance Forslund takes over the role of Ginger Grant.
