28 Days Later · reception & legacy

How 28 Days Later has been received, argued over, and remembered.

The arc

A sleeper hit on release — a scrappy DV-shot British horror that became a word-of-mouth phenomenon in its 2003 US run — it's since been canonised as the film that resurrected the zombie genre for the 21st century, with the 2025 release of 28 Years Later cementing its elder-statesman status.

What's debated

The eternal fan fight: are the infected actually zombies (they're not dead, and they RUN) — a pedantic-but-beloved debate that doubles as the fast-vs-slow zombie schism the film ignited.

Its footprint

The image of Cillian Murphy wandering an utterly deserted London is one of modern cinema's most referenced openings — during the 2020 COVID lockdowns, photos of empty Westminster Bridge were instantly captioned '28 Days Later'. Its sprinting infected rewired the entire genre, from Dawn of the Dead '04 to World War Z.

Where it stands

Firmly in the modern horror canon — a 'you must have seen this' entry that launched Cillian Murphy, and its long streaming unavailability in the US only fed its rewatch mystique.

Named by the director

Influences Danny Boyle has publicly named — the director's own word, distinct from the inferred lines of influence.

• George A. Romero — Boyle openly acknowledged the film's debt to Romero's Dead trilogy, framing 28 Days Later as an homage to and update of his infected-society template.
