Cast Fact Table

Who plays the kid and Jimmy in 28 Years Later?

The child at the center of 28 Years Later is portrayed by Alfie Williams, who plays Spike—the 12-year-old son of Jamie and Isla. Spike represents the first generation born entirely within the rage virus-ravaged world, having no memory of life before the outbreak.

His storyline drives much of the film’s emotional core as he becomes increasingly curious about the world beyond the island’s walls. The character faces the challenge of understanding both the infected threat and the human dangers posed by survivors who have developed their own brutal social structures.

The Jimmy Crystal Characters

Jack O’Connell stars as Sir Lord Jimmy Crystal, the charismatic but sinister leader of an island-based cult. His character draws inspiration from the infamous Jimmy Savile, creating a disturbing parallel between the film’s fictional villainy and real-world predatory behavior.

Rocco Haynes plays Young Jimmy Crystal, depicting the character as a child before he transforms into the cult leader. This backstory element suggests how the post-apocalyptic environment enabled the emergence of such figures.

Supporting Cult Members

Erin Kellyman appears as Jimmy Ink, one of the cult members serving under Jimmy Crystal. Additional cult roles include Haley Flaherty as Jimmy’s Aunty, Harriet Taylor as Jimmy’s Cousin Delilah, and Hannah Allan-Robertson as Jimmy’s Sister.

Christopher Fulford plays Sam, Jamie’s friend who has established himself as a resident of the island community. Stella Gonet portrays Jenny, a member of the island’s leadership council, suggesting a structured governance system has developed among the survivors.

What is the cast of 28 Years Later: The Bone Temple?

The Bone Temple serves as the direct sequel to 28 Years Later, having been shot back-to-back with its predecessor. Nia DaCosta directs this follow-up, marking the first time the franchise has been guided by a different filmmaker in the main series.

The cast for The Bone Temple remains partially unconfirmed as of the current period. While the core ensemble from the first film likely returns, specific role details and additional casting announcements have not been fully disclosed across official sources.

Confirmed Details

• The film is scheduled for release in January 2026
• Nia DaCosta directs, following her work on Candyman and The Marvels
• Danny Boyle and Alex Garland continue their involvement as producer and writer respectively
• The narrative continues from the events established in 28 Years Later

Remaining Uncertainty

No sources confirm which cast members appear in The Bone Temple beyond the core ensemble likely returning. Full cast credits for the sequel have not been publicly released, and production details remain limited until closer to the release date.

Is the cast of 28 Years Later on Netflix?

No sources confirm Netflix distribution, streaming, or involvement with 28 Years Later. The film received theatrical distribution through standard cinema release channels, with Fandango listing the production and Odeon providing promotional coverage for theatrical audiences.

The franchise has not historically maintained a streaming presence; the original films received traditional theatrical releases and subsequent home video distribution. Current official sources including Wikipedia, Fandango, Rotten Tomatoes, and Odeon present the film as a theatrical release with no indication of streaming platform partnerships.

Current Distribution Status

• Theatrical release confirmed for 2025

Cast Announcement Timeline

2. May 2024: Jack O’Connell joined the production in the role of Sir Lord Jimmy Crystal
3. June 2024: Erin Kellyman was announced as part of the cast, filling a supporting role in Jimmy’s cult

The announcement sequence followed a measured approach, building anticipation through staggered casting reveals rather than a comprehensive cast list release. This strategy aligned with marketing efforts that emphasized the returning creative team of Boyle and Garland while highlighting the new ensemble.

Confirmed vs Rumored Cast

Official sources including Wikipedia, Fandango, Rotten Tomatoes, and Odeon consistently confirm the primary cast members listed above. Smaller supporting roles vary slightly across sources, suggesting ongoing credits updates as the production moved toward release.

Cast in Franchise Context

The cast of 28 Years Later represents a deliberate departure from the original trilogy’s ensemble. While Cillian Murphy’s Jim served as the emotional anchor of the first three films, his character does not appear in this continuation—though he remains connected as executive producer.

The franchise has historically featured British actors in leading roles, a tradition maintained through Comer, Taylor-Johnson, Fiennes, and O’Connell. However, the introduction of Edvin Ryding as a Swedish soldier signals potential expansion of the geographical scope beyond the United Kingdom settings of previous entries.

The focus on a family unit—Jamie, Isla, and their son Spike—echoes the domestic emotional core that drove 28 Days Later. Yet the addition of the Jimmy Crystal cult element introduces a new form of human conflict that complements the biological threat of the infected.
