The Evolution of Actor Duplication in Cinema from Buster Keaton to Modern VFX

The New York Times article explores the evolving cinematic technique of duplicating a single actor on screen, a practice that has become increasingly prevalent in 2025. The piece highlights recent films such as ‘Mickey 17,’ ‘The Alto Knights,’ and ‘Sinners,’ each featuring lead actors—Robert Pattinson, Robert De Niro, and Michael B. Jordan—playing multiple roles simultaneously. The article delves into the historical roots of this technique, tracing it back to Buster Keaton’s 1921 silent short ‘The Playhouse,’ where in-camera effects like masking and double exposure created multiple versions of Keaton in a single frame. In the 1961 classic ‘The Parent Trap,’ the split-screen technique became the standard for such visual trickery. Today, digital facial replacement and advanced VFX tools allow seamless blending of multiple performances by one actor, making these illusions more convincing than ever. The article positions these visual effects not just as gimmicks, but as storytelling tools that open up new possibilities for character development and narrative complexity.
