Bob Denver’s wife, Dreama Denver, had a few roles during both the running of the show and the last movie. During the original series, she had a role in a single episode as a cavewoman that had been hiding on the island since prehistoric times.
During “The Harlem Globetrotters on Gilligan’s Island,” she reappeared as Lucinda, the overly-punctual secretary for Mrs. Howell. Other than these small roles and an appearance in the TV movie “Scamps,” Dreama didn’t act much. She did appear in several episodes of shows like “Entertainment Tonight” about “Gilligan’s Island.” She also published a book about her marriage to Bob.
Will they ever escape?
One of the most popular theories about the show is that the characters will never get off the island. In fact, they're all dead, and they're in purgatory to work off bad karma. It's common practice to give sitcom characters one of the seven sins (greed, envy, sloth, etc.) and see how they interact, or at least to give them depth.
While this was a fun theory – and the number of characters matches nicely with the number of deadly sins – it was eventually proven to be untrue, as the characters finally got off the island in the second reunion movie. However, we still enjoy watching them fail just because of their sinful faults.
Acting for two
In both of the animated series – “The New Adventures of Gilligan” and “Gilligan's Planet” – the characters of Ginger and Mary Ann are voiced by the same person. In “The New Adventures,” it was actress Jane Webb (pictured below on the left) who provided the voices, as Tina Louise refused to return, and Dawn Wells was busy.
This prompted a change to Ginger, becoming a platinum blonde instead of having Louise's red hair. In “Gilligan's Planet,” Wells was available, so she voiced both of the characters. In addition, in an original live-action episode, Tina Louise plays both Ginger and an identical stranger Eva Grubb.
The legacy of the show is still felt by the cast
Even though Gilligan’s Island officially ended almost a decade ago, the now senior stars still find themselves in various situations that remind them just how big of an impact the show had on the entertainment culture. Bob Denver recalls taking his wife out to a fancy dinner restaurant in Chicago. The band for that night was playing classical music. Upon entering the restaurant, they decided to change the score, and suddenly began playing “The Ballad of Gilligan’s Island.”
Another funny thing happened in 2001 when Russell Johnson was invited to speak at a biochemical conference in San Francisco (despite not being an actual professor). He recalls meeting 400-500 Ph.D.’s there and in his words, “every one of them was a Gilligan’s Island fan.” It sounds like a spectacular experience.
The hidden purpose of the character’s distinct personalities
It’s not a coincidence that each of the show’s characters has a unique personality, history, and style. Sherwood Schwartz, the show's creator, intended from the beginning to create a diverse cast of characters that would each represent a different relatable part of society, from the rich and successful Thurston Howell to the inventive Professor Roy Hinkley.
The goal of this large difference in characters was to make the show thought-provoking rather than just funny. The dynamics of the cast, their need to find different ways to live together and make the best of the situation was a brilliant plot tool. It made for some extremely funny, but also very deep and rewarding, experiences.
