14 Things You Never Knew about ‘Gilligan’s Island’

4. Do you know their full names, first and last?

Sure, you can rattle off Gilligan, the Skipper too, the millionaire and his wife, the movie star, the Professor and Mary Ann, no problem. But, do you remember their real names? Let’s see, the millionaires are pretty easy as they were often mentioned by the names of Thurston Howell III and Lovey Wentworth Howell. Ginger Grant is pretty easy too – the movie star wasn’t shy about promoting her famous name. The Skipper and the Professor were rarely referred to by anything but their job titles (how rude!), but they actually were ascribed the names of Skipper Jonas Grumby and Professor Roy Hinkley. Mary Ann, the Kansas farm girl, was actually Mary Ann Summers, for those who want to know. As for the titular character, no one really knows if Gilligan was the First Mate’s first name or last name. There is some speculation that Sherwood Schwartz intended his name to be Willy Gilligan in the planning stages, but there’s no real evidence to that. He is never referred to as anything but a one-namer – kind of like Madonna and Cher.
