We've only just begun to dig into the post-apocalyptic nightmare that is 28 Years Later, with the second part of director Danny Boyle and screenwriter Alex Garland's 28 Days Later reunion set to hit cinemas.

Directed by Candyman's Nia DaCosta, 28 Years Later: The Bone Temple picks up where the third film in the franchise left off. Having left the safety of his home on Holy Island, Spike (Alfie Williams) has found himself caught up with the problematically inspired Jimmy Crystal (Jack O'Connell) and his blonde-wigged gang.

Meanwhile, the iodine-washed Dr. Kelson (Ralph Fiennes) has a terrifying path ahead of him, as we get a glimpse into his past through family photographs. But the trailer shows Jimmy's crew walking through Kelson's bone-built memento mori structure, and Kelson looking rather...angry about it, so anything could happen.

Overlaid in the trailer is science fiction author Arthur C. Clarke speaking in a 1964 BBC show called Horizon: The Knowledge Explosion, saying that "trying to predict the future is a discouraging, hazardous occupation." It fits.
