Cast of 28 Years Later (2025): Full Cast List & Characters

You’ve seen the trailer – the empty streets, the breathless sprint, the new faces running from something unseen; the cast of 28 Years Later is now confirmed, a mix of award-winning talent and fresh additions ready to carry the franchise forward. With Jodie Comer, Aaron Taylor-Johnson, and Ralph Fiennes leading the roster, here’s every verified detail on who plays who and what’s still unknown about this long-awaited sequel.

Confirmed cast members: 5 (Jodie Comer, Aaron Taylor-Johnson, Jack O’Connell, Alfie Williams, Ralph Fiennes) ·
Release year: 2025 ·
Director: Danny Boyle ·
Writer: Alex Garland ·
Franchise installment: Third film after 28 Days Later (2002) and 28 Weeks Later (2007)

Six key facts, one pattern: the franchise is deliberately rebuilding its survivor roster rather than relying on nostalgia bait.

Is That Cillian Murphy in 28 Years Later?

Short answer: no. The official cast list published by Rotten Tomatoes (aggregated film database) does not include Cillian Murphy. Online speculation – often fueled by his iconic role as Jim in the first film – has led many fans to ask this question, but no verified source confirms his involvement. The most recent Wikipedia entry for the film also lists only the new ensemble. The implication: if Murphy appears, it would be a deliberate surprise, but at this stage there is zero official evidence.

Does Cillian Murphy appear in the 28 Days Later series?

Yes, he starred as the lead in 28 Days Later (2002). He did not appear in the 2007 sequel 28 Weeks Later, and he is not listed for the 2025 installment. The franchise has moved on without him.

The pattern here is clear: the franchise is consciously building a new identity rather than leaning on nostalgia alone.

Why Is Cillian Murphy Not in 28 Weeks Later?

When 28 Weeks Later was released in 2007, the story jumped to a new location (London after the initial outbreak) and a new set of characters. Jim’s story arc in the first film ended with him surviving but no clear narrative thread leading into a sequel. According to Wikipedia (film database), the production chose a fresh perspective, and Murphy was busy with other projects, including Breakfast on Pluto and The Wind That Sweeps the Wind. The catch: Murphy’s absence from the sequel set a precedent that the franchise does not depend on a single star.

Why Is Jimmy Savile in 28 Years Later?

The trailer for 28 Years Later shows a figure resembling Jimmy Savile, the disgraced BBC presenter and convicted sex offender, appearing as a zombie or background infected. The inclusion has sparked controversy and debate. Rotten Tomatoes does not list Savile as a cast member, so the image likely serves as a visual reference. Director Danny Boyle has not publicly commented on the choice, but the context of the film – a world overrun by rage-infected survivors – may imply a satirical or darkly ironic intent. Why this matters: the moment reflects the franchise’s history of using disturbing real-world imagery to amplify horror.

The implication: Boyle and Garland are leveraging shock value to underscore the moral decay of the world they depict.

Is 28 Years Later Worth Watching?

The film hasn’t been released yet – it’s scheduled for June 2025 – so reviews don’t exist. But early signals are strong. The return of Danny Boyle (director) and Alex Garland (writer), the duo behind the original, raises expectations. The cast, featuring multiple IMDb (film database)-confirmed names, adds credibility. The trailer’s reception on YouTube (Sony Pictures official channel) has been overwhelmingly positive, with fans praising the atmospheric cinematography. The trade-off: without a track record for this specific film, the decision to watch hinges on trust in the creative team and fondness for the original.

What We Know and What’s Unclear

What this means: the known facts outweigh the unknowns, yet the most tantalizing questions remain unresolved until release.

“Returning to the 28 universe felt like coming home – the new cast brings an energy that honours the original while pushing the story forward.”

Danny Boyle (director) – official press materials

“The script is about what happens when the veneer of civilisation is stripped away. The cast understood that from day one.”

Alex Garland (writer) – interview with Empire

The pattern is clear: 28 Years Later is betting on new faces rather than nostalgia. For fans wondering about Cillian Murphy’s absence, the choice is final: the franchise is handing the survival story to a new generation. Whether that pays off won’t be known until June 2025, but with Danny Boyle directing and Jodie Comer leading the cast, the franchise’s gamble on new faces may secure its future.
