Robby is a 1968 family film written and directed by Ralph C. Bluemke. It is a modernday retelling of the Daniel Defoe novel Robinson Crusoe in which the main characters are portrayed as children. The film deals with many themes, including friendship, homesickness, racial blindness and naturism. It is unusual for a family film in that it contains extensive, explicit nudity involving young boys.
It is not long before Robby himself abandons his own clothes and the two friends scamper around the island naked and free without adult supervision. Robby teaches Friday how to speak English, and in turn Friday teaches Robby how to swim. Together, the two boys survive on the island, with only each other to rely on. They build a shelter and fish for sustenance. They are faced with threats of poisonous snakes and cannibals, of which they find evidence in the form of human remains, as well as a stranger who mysteriously appears on their island one night.Writerdirector Ralph C. Bluemke originally conceived the idea of retelling the classic Robinson Crusoe story with children as the principals while working at a bank in 1960, seven years before filming would even begin. ........
