Two decades after 28 Days Later redefined the zombie genre with its visual storytelling, director Danny Boyle and screenwriter Alex Garland have returned with 28 Years Later, a long-awaited sequel that builds upon — and strays — from the DNA of the 2002 classic.

More than two decades after the release of his zombie apocalyptic horror hit "28 Days Later", director Danny Boyle is returning to the franchise with a fresh set of eyes and a twist on a new technology.

Director Danny Boyle has admitted it was a "nightmare" filming naked zombies for new horror movie 28 Years Later because they had strict rules in place to protect the film's child star Alfie Williams.
