28 Years Later, a sequel to the 2002 zombie movie 28 Days Later, was reportedly shot using an iPhone 15 Pro Max. Wired did some investigating after seeing an on-set image shot by a paparazzo, and says that "the use of Apple smartphones as the principal camera system on 28 Years Later was subsequently confirmed to Wired by several people connected with the movie." This news comes shortly after Apple spent a considerable amount of time touting the iPhone's capabilities as a video camera during its iPhone 16 Pro announcement event.

Looking at the on-set image posted by Just Jared, you'd be forgiven for not spotting immediately spotting the phone. Like with many 'Shot on iPhone' productions, it's buried beneath tons of gear, including what appears to be an external lens, monitor, matte box, and more.

The movie's director, Danny Boyle, and cinematographer, Anthony Dod Mantle, are no strangers to using cutting-edge and sometimes unusual cameras to make their movies. In 2009, Dod Mantle's work on Slumdog Millionaire – also directed by Boyle – earned him the first Oscar for Best Cinematography awarded to a movie shot mainly using digital cameras instead of film. The pair also worked together on 127 Hours, a movie partially shot on Canon DSLRs.

Perhaps the most relevant precedent is 28 Days Later itself. Boyle and Dod Mantle shot much of it using the Canon XL1, a CCD camcorder that recorded to DV tapes. In the 2012 documentary Side By Side, Boyle talks about how using several of the relatively inexpensive cameras helped them shoot the iconic scene where Cillian Murphy walks through an empty and trashed London despite the production not having enough money to shut down the city.

Image quality-wise, the iPhone 15 Pro – which can shoot Log footage at 60fps in ProRes – is vastly superior to the XL1. Talking about shooting 28 Days Later in Side By Side, Boyle reminisced, saying, "if you were in a wide shot with a small figure in it, they were just two or three pixels. I mean there was nothing there, there was just the color."

Still, shooting 28 Years Later with iPhones is an interesting choice. The original movie had an estimated budget of around $8 million – that wasn't a lot of money to shoot a film with in 2002, so it's easy to see why they didn't want to spend a ton on camera gear. 28 Years, meanwhile, has a reported budget of around $75 million.

While that's relatively modest by today's standards, entry-level cinema cameras have gotten so inexpensive that the crew almost certainly could've afforded them if they'd wanted to use them. For reference, the 2023 sci-fi film The Creator had an estimated budget of around $80 million and was famously shot using a Sony FX3. Alex Garland, the writer of 28 Days Later and 28 Years Later, also recently shot a $50 million movie that made use of the DJI 4D-6K.

We likely won't know why this decision was made until the crew publicly acknowledges the iPhone's role in filming, but when they do, they'll likely talk about it extensively. The decision to shoot on smartphones has historically been a big focus in the PR cycle leading up to the release of films shot on them, such as 2015's Tangerine or 2018's Unsane.

According to Wired, the iPhone wasn't the only camera used to shoot 28 Years Later: unspecified action cameras were also used to film scenes involving farm animals. The outlet says Apple was informed the production would be using iPhones and that the company "provided technical assistance to the moviemakers."

28 Years Later is set to release in June 2025 and will reportedly be the first of three new movies in the franchise. Its sequel is currently being called 28 Years Later Part II: The Bone Temple, though there's currently no information on what it's being shot with.
