Four Sided Triangle (1953)

Four Sided Triangle (1953), directed by Terence Fisher.

Three childhood friends, reunited as adults, build a matter replicator in an old shed, anticipating the computer startup garage-works of later decades. Romance? With two men and one woman, not all can be made happy. What if they replicated the woman? Even if she consented, wouldn't both versions still love the same man?

This is in no sense an important or exceptional film. I review it only because I thought I knew 1950s science fiction films and had never heard of it until recently.

Its good features:

Netflix has the DVD.
