Page "Gilligan's Island" Paragraph 26

The second theme involves visitors to the " uncharted " island.

One challenge to a viewer's suspension of disbelief is the frequency with which the castaways are visited by people who do nothing to assist them.

Some have hidden motives for not assisting the castaways.

Others are simply unable to help, incompetent, or are prevented from sending messages by Gilligan.

Bob Denver, Jim Backus, and Tina Louise each had feature episodes in which look-alikes come to the island ( who were, of course, played by themselves in dual roles ).

The island itself is also home to an unusual assortment of animal life, some native, some visiting.
