Cheapskate
In the show, Jim Backus’ character was a big-spending millionaire. In real-life, he was actually a frugal person and many stories of the crew involved Backus “forgetting his wallet” when it was time to pay for a meal. This forced other Gilligan’s actors to pay for his order. He did this repeatedly and the whole cast and crew keep on reminding him by teasing him all the time.
On-Set Diva
During the entire period of filming, there were many exceptions that had to be arranged for Tina Louise. She felt she was misled of her role in the show, thus everyone had to adjust. She was told by her agent that the role is of a movie star on the castaway island. She had no idea that the show would revolve around her character.
