Four Sided Triangle (1953) • Discape

She lived two amazing lives under his evil spell.

Two brilliant scientists fall in love with the same woman and, after she chooses one of them, the rejected suitor uses their experimental technology to duplicate her. But the copy, though identical in appearance, develops her own feelings—complicating their already fragile love triangle. This thoughtful British sci-fi drama explores identity, obsession, and the unintended consequences of tampering with human emotion.
