Danny Boyle and Alex Garland’s world of fleet-footed zombies is impressive in 28 Years Later, which shows its first official trailer.

The third installment in the 28 Days Later franchise sees Boyle and Garland return to their respective roles in the franchise as director and writer, having served as exec producers on Juan Carlos Fersnadillo’s 2007 sequel “28 Weeks Later.”

The film is led by franchise newcomers Aaron Taylor-Johnson, Jodie Comer and Ralph Fiennes, seen throughout the creepy trailer fighting off zombies.

Though original movie star Cillian Murphy had been reported to be reprising his role as Jim in addition to being an executive producer, he appears absent from the trailer and is not listed as a cast member in the promotional material. However, the new trailer features a particularly jarring clip of a zombie that some on social media speculated bears resemblance to the Oscar winner.

Other new cast members include Erin Kellyman and Jack O’Connell.

The film’s official synopsis reads: “It’s been almost three decades since the rage virus escaped a biological weapons laboratory, and now, still in a ruthlessly enforced quarantine, some have found ways to exist amidst the infected. One such group of survivors lives on a small island connected to the mainland by a single, heavily-defended causeway. When one member of the group leaves the island on a mission into the dark heart of the mainland, he discovers secrets, wonders and horrors that have mutated not only the infected but other survivors as well.”
