The early classic
"Forbidden Planet" for me.
Back in late high school at the end of the 70's, we were given the choice of studying this movie or go the dry road and study the original Shakespeare play "The Tempest". We took the movie and it's been my favourite sci-fi ever since. The fact that its premise is based on the Tempest just serves to reinforce my respect for it. The Tempests' main character, Prospero, employed magic to control his environment on the island, where Forbidden Planet's Morbius utilised technology. Wonderful parallels that really work. Technology, taken to its ultimate conclusion, will be indistiguishable from magic. Thanks for that observation Arthur C. Clarke
