No, that wasn't a zombified Cillian Murphy in the first trailer for 28 Days Later - at least not according to a crew member who worked on the film.
One shot from the teaser shows a zombie - though the infected are not technically zombies - that looks a hell of a lot like the Oppenheimer Oscar-winner, which led to speculation that this could be Murphy's character from 28 Days Later, Jim.
It was a reasonable enough theory given the amount of time that's passed since the first movie, although bringing an actor of Murphy's calibre and status back just to play a mindless monster would have been an odd choice. Also, a set photo of the actor as a very-much-human Jim did the rounds when the film was shooting earlier this year (though there was always a chance this was for a flashback scene).
There's a chance PJ here is simply trying to throw people off track, but we doubt it very much.
Star Ralph Fiennes revealed the basic premise during an interview with IndieWire earlier this year.
“It centers on a young boy who wants to find a doctor to help his dying mother. He leads his mother through this beautiful northern English terrain. But of course, around them hiding in forests and hills and woods are the infected. But he finds a doctor who is a man we might think is going to be weird and odd, but actually is a force for good.”
You can check out Sony's official synopsis below.
"It’s been almost three decades since the rage virus escaped a biological weapons laboratory, and now, still in a ruthlessly enforced quarantine, some have found ways to exist amidst the infected. One such group of survivors lives on a small island connected to the mainland by a single, heavily-defended causeway. When one of the group leaves the island on a mission into the dark heart of the mainland, he discovers secrets, wonders, and horrors that have mutated not only the infected but other survivors as well."
Directed by Danny Boyle and written by Alex Garland, 28 Years Later is produced by Andrew Macdonald, Peter Rice, Bernard Bellew, Boyle, and Garland. Cillian Murphy executive produces. The cast also includes Jodie Comer, Aaron Taylor-Johnson, Jack O'Connell, Alfie Williams.
The movie is set to hit theaters on June 20, 2025.
