This article contains major spoilers for 28 Years Later.
28 Years Later viewers are still reeling from that shocking ending.
Much has already been made of the fact that, in the film鈥檚 final moments, teen protagonist Spike stumbles upon a renegade cult gang who appear to have modelled their appearance on the disgraced TV presenter Jimmy Savile, complete with colourful shellsuits and platinum blond wigs.
It鈥檚 worth pointing out that 28 Years Later is set in an alternate world in which the deadly 鈥渞age virus鈥 begins to spread in 2002, completely disrupting society, meaning it鈥檚 entirely likely that in the timeline seen on screen, the allegations about Savile were never actually made public.
However, there鈥檚 another wild part of the ending that has also stayed with fans.
Before we get into that, though, let鈥檚 quickly flash back to the very beginning of the film.
The first scene of 28 Years Later features a group of youngsters who are huddled together to watch a vintage episode of Teletubbies, before all hell breaks loose, and a member of the 鈥渋nfected鈥 wreaks havoc on the youngsters (the Teletubbies scene was first teased in a 28 Years Later trailer released earlier this year).
We learn at the end of the film that cult leader Sir Jimmy Crystal 鈥 played by Jack O鈥機onnell 鈥 was one of the survivors of this attack, with some also questioning whether or not those colourful tracksuits were also a nod to the Teletubbies, as well as another group of 90s and 2000s kids鈥 TV icons, the Power Rangers.
But that鈥檚 not the only callback to the Teletubbies, though, with the gang鈥檚 unpredictable fight scene being accompanied by a rock cover of the show鈥檚 iconic theme tune (which famously topped the UK singles chart back in 1997 with a bit of help from Simon Cowell).
28 Years Later director Danny Boyle has already teased that the gang Spike encounters at the end of the film will form a major part of the film鈥檚 sequel, which is due for release early next year.
He claimed: 鈥淭he role of Jack O鈥機onnell鈥檚 character and his family, which is a replacement, really, for the family he loses at the beginning of the film, is to reintroduce evil into what has become a compassionate environment.
鈥淚 asked Alex [Garland, who wrote both films] right at the beginning to just tell me what鈥檚 the nature of each of the films, and he said that the nature of the first film is about family. The second film is about the nature of evil. And you鈥檙e about to meet a lot more of them when it鈥檒l be more appropriate to talk about them in the second film.鈥
The Trainspotting director previously said that he hopes 28 Years Later and its sequel, subtitled The Bone Temple, will form the first two instalments of a new trilogy, the third of which is not yet greenlit.
