Three Identical Strangers is a 2018 documentary about triplet brothers — Robert Shafran, Eddy Galland, and David Kellman — who were separated at birth and adopted by different families without being told they had siblings. They accidentally discovered each other as young adults in the early 1980s, becoming media sensations — “miracle” brothers reunited. But the feel-good story turns dark when they learn they were separated intentionally as part of a secret psychological study on nature vs. nurture, with researchers observing their lives for years. The film explores ethics, trauma, and the lifelong impact of experiments done without consent.
