Gilligan's Island first show was released 1964. It ran for 3 seasons and had 99 episodes. The first 36 were in Black and white and the rest in color. It was One of my favorite comedy.
This pilot was never aired. the show was restructured and the characters and song are changed. One thing it very different in this pilot then the opening show broadcast, Do you know what it is? Hint it has to do with the fish. Leave your guess in the comments. I will show and tell on Monday.
Enjoy Running time 24:26.
