The Harlem Globetrotters on Gilligan's Island (1981)

Those amazing "court jesters" team up with the Gilligan gang to save the island and its rare "Supremium" ore from an evil billionaire!

The Harlem Globetrotters' chartered plane crash lands on the atoll inhabited by the happily marooned Gilligan and fellow castaways, and they all must play basketball against a specially programmed squad of robots controlled by a mad scientist.
