Walter Pidgeon - "Stop it, Robby! Don't let it in! Kill it!"
Leslie Nielsen - "It's no use. He knows it's your other self."
The Sci Fi movie Forbidden Planet is based on Shakespeare's play The Tempest, which is full of
deep philosophical ideas closely parallelling those of the Avadhutas of India.
The deeper ideas didn't really make it into the film, but it reminds us how universal Shakespeare's work is that it can be adapted into such a different genre.
I love the way the Krell (aliens a million years ahead of us technologically) clung nostalgically to pre-digital ammeters (see background of poster). Perhaps this was their undoing.
