John Williams, later famous for scoring Star Wars and Jurassic Park, wrote the original theme song for the unaired pilot of Gilligan's Island. The nearly two-minute track featured lyrics sung by creator Sherwood Schwartz in a Caribbean accent. The pilot, titled Marooned, led to significant changes before the series aired.
CBS selected the concept for development but rejected the pilot due to multiple issues. Three cast members were replaced, and the theme song was rewritten by Schwartz and composer George Wyle. Williams still provided incidental music for the show's first two seasons. The original pilot remained unseen until a 1992 TBS marathon. Williams later earned five Academy Awards, three Emmys, and 20 Grammys, along with a record 51 Oscar nominations.
