28 Years Later is an upcoming post-apocalyptic horror film directed by Danny Boyle, from a screenplay he co-wrote with Alex Garland. Produced by Columbia Pictures in association with BFI, DNA Films and Decibel Films, it serves as a sequel to both 28 Days Later (2002) and 28 Weeks Later (2007). It stars Cillian Murphy reprising his role from 28 Days Later, alongside Aaron Taylor-Johnson, Jodie Comer, Ralph Fiennes, and Jack O'Connell.
I loved 28 Days Later, thought 28 Weeks Later was just okay, and have basically no interest in 28 Years Later.
28 Centuries later is going to be great though
These kind of sequels are maybe 50/50. The new Blade Runner was great, for example.
