When the first trailer arrived for “28 Years Later,” the third installment in Danny Boyle and Alex Garland’s masterful “28 Days Later” series of horror films, it was scary, filled with gruesome images of zombies and a dystopian world.

Victor Halperin's White Zombie (1932) marked the inception of the zombie film, while George A. Romero's Night of the Living Dead (1968) established the framework for the modern genre. The release of 28 Days Later in 2002 reinvigorated interest in zombies.

Years Later is the third film in the long-running series, following director Danny Boyle’s audacious original from 2002, 28 Days Later — it gave us fast zombies! — and mostly ignoring 2007’s 28 Weeks Later.
