When you set out to create a show like Fantasy Island you have to be well read on history and have one good imagination. Glad to say that Fantasy Island showed a good deal of both in their episodes.
One episode I well remember was a pair of women were real big into the Civil War and desired to go back and live the genteel life that Scarlett O'Hara and her family had on Tara. Fantasy Island brought them back all right, but showed them the downside of that era and I'll say no more on the story. The morale of that show was be happy in your own backyard.
Host and impresario of Fantasy Island was the mysterious Mr. Roarke played by Ricardo Montalban. In interviews Montalban said that he never got the real career role on the big screen that defined other of his contemporaries. But on the small screen Montalban got two of them, Mr. Roarke and Khan on Star Trek which went to the big screen also. What powers Roarke drew on to show his guests what they really thought was ideal was left open to the imagination.
For all but one season Montalban had his dwarf companion Herve Villechaize and these two had a gentle and playful repartee. Villechaize had a sad and tragic life, but Fantasy Island left him with a career role and an identity that will linger.
I could never see this show revived because Montalban and Villechaise had such a special chemistry for the small screen.
