Gilligan's Island

Just sit right back and you'll hear a tale... So now the seven castaways are stranded on the legendary fictional island. This is one of the many pilot episodes that sold, just didn't get aired (Such as Captain Jack, which was renamed Leave it to Beaver), instead they altered the show drastically, replacing actors, characters, and the theme song.

A tsunami swamps the island, sweeping the castaways into the ocean in a floating hut. They finally get rescued, but find that civilization isn't as civilized as they thought.

How the series was developed.

The famous Harlem Globetrotters crash land on Gilligans Island, immediately dispatching a terrifying 'shark' by throwing basketballs at it. A mad doctor and his accomplice plan to take over the island for its rich energy supply by scaring off Gilligan and his buddies, but it soon settles to a basketball match between the doctors robots and the aforementioned Globetrotters
