Directed by Nia DaCosta and written by Alex Garland, the post-apocalyptic horror sequel 28 Years Later: The Bone Temple is scheduled to arrive in theaters on January 16, 2026. The film is the second part of a new trilogy and serves as a direct follow-up to 28 Years Later, which was released earlier in 2025.

The story picks up in a dangerous, post-apocalyptic Britain where the "Rage Virus" still exists, but the biggest threat is now other people. The plot follows a teenager named Spike (Alfie Williams), who has been taken in by a terrifying cult known as the "Jimmies." This group is led by Sir Jimmy Crystal (Jack O'Connell). Meanwhile, Dr. Kelson (Ralph Fiennes) is living at the "Bone Temple," a strange place where he tries to study the infected.

28 Years Later: The Bone Temple features returning stars like Aaron Taylor-Johnson, Erin Kellyman and Cillian Murphy, who returns as Jim from the original 2002 movie.
