Film Synopsis
Four Sided Triangle (1953) follows two lifelong friends who invent a machine that can reproduce physical objects exactly as they are.

This British science fiction drama blends romantic obsession, ethical dilemmas, and speculative technology in a cautionary tale about scientific ambition and human desire.
