’28 Years Later’ was shot on iPhone 15s. The actors loved it.

One of the scariest films of the year, 28 Years Later, used iPhones to film key scenes.

Director Danny Boyle and screenwriter Alex Garland reunite almost 28 years after their groundbreaking 2002 film 28 Days Later, delivering a gloriously horrifying cinematic experience in their latest film.

Also returning is cinematographer Anthony Dod Mantle, whose use of digital camcorders defined 28 Days Later. Here, Boyle and Mantle use a host of cameras, including 20 adapted iPhone 15s, all deployed to capture Boyle’s go-to 2.76:1 widescreen aspect. But what effect does this produce in 28 Years Later, and what does it mean for the actors in front of the many lenses?
