Forbidden Planet My favorite, boy did I have nightmares after seeing it as a kid. I have the music and play it from time to time Way Far Out!!!
A remake today would probably have the Krell going extinct because of global warming, or some other such nonsense, instead of them forgeting their innate selves, which I always associated with liberalism ( like how they blame an object instead of human nature.)
Looks like the same saucer was used in some twilight Zone episodes .
