Gilligan’s Island premiered on CBS in September 1964, and ran through April 1967. Wells, who had beat out 350 other actresses to play wholesome Mary Ann, also appeared in the follow-up TV-movies Rescue from Gilligan’s Island (1978) and The Castaways on Gilligan’s Island (1979) — the latter of which saw Gilligan & Co. get re-stranded on the same island, get rescued, and then turn the isle into a vacation destination.
