Jim dies at the end.After receiving a nasty gunshot wound to the stomach, the camera freezes as Jim's friends desperately try to rush him to a hospital. A caption appears with '28 days later...' written on, just like at the beginning. After a quick-cut summary of Jim being patched up at the hospital, he wakes up in a little house in the country with his friends. They're soon spotted by a plane sent by the outside world, with the possibility of rescue on the way. Notably, this last sequence is shot differently from the rest of the movie; the rest of the movie is shot with a 'rough' digital camera, but the epilogue sequence is shot with traditional film stock. Some believe this indicates that Jim didn't survive his injuries; this is his idea of 'paradise' after the weeks of torment he's just gone through. It helps that, in the original drafts of the script, and the alternate endings shot and, in some screenings and on the DVD, played after the credits, Jim did die; the film-makers decided this would be a bit too much of a Downer Ending.
Jim is dead before the movie starts.The movie opens with Jim, naked, in an abandoned hospital, having apparently woken from a coma caused by his getting run over by a car. This raises a few questions - why is he naked, and not in a hospital gown? Why was he seemingly the only patient left in the hospital? Why is his room so trashed? These points — coupled with the surreal, hellish experiences he goes through before the ultimately hopeful ending and the slightly Jesus-like way in which he is framed in the opening shot — make it look like Jim died when he was hit by the car. The entire movie is his soul going through torment in purgatory before finally being accepted into paradise. That's right, folks - it's an actual Everyone Is Jesus in Purgatory story we got here...
Jim is crazy as a bag of hammers.The zombies are real, but Jim is not a good guy. All the male competition for the few female survivors? Dead as hell.
This movie and I Am Legend take place in the same universeScientist developed a cure for cancer. In the USA, they tested it on humans; in the UK, they tested it on monkeys first. The Dark Stalkers and the "Infected" are the same, only the American Infected developed an allergy to the sun due to its cure being tested on people with cancer. Jim wakes up at the same moment I Am Legend starts.
Left 4 Dead takes place in the same universe as the 28 seriesSelf explanatory, really. The special infected and the change in infection times can be hand-waved by the virus adapting to the new environment of a fantasy-counterpart Pennsylvania. That new government health agency that you see on all the evacuation posters was formed after all the stuff that happened in England.
The Rage 'virus' isn't a virus at allRage is a curse carried by blood. It releases the negative energy in everything it touches. This explains how it works so damn fast.
A side effect of the Rage virus is increased production of blood.Or alternately, the body expelling all its bodily fluid, not just plain blood and vomit. Private Mailer should not have that much blood in him.
Jim is a long-term guest at Arkham AsylumHe got dosed with his own fear toxin in Batman Begins. Everything that happens in 28 Days Later is what his mind is experiencing while he is having his drug-induced Freak Out!.
Finland survives the virus.The fighter pilot in the end speaks Finnish in the radio. This suggest the rescue operation is not an international effort, but Finland as a country manages to keep its government and infrastructure intact, while the rest of Europe is ravaged by the Rage virus. Finland becomes the leading nation of the rebuilt EU, although graciously accepting American assistance with troublesome outer island regions like Britain.
The virus mutates before it gets to the United States...Everyone there turns into a shufflin' zombie, though.
Sgt. Doyle was once called Clint BartonPurely based on the fact that he is an expert marksman and sniper... who's actor became the World's Greatest Marksman
The infection takes longer to kick in than it appears.The virus works by causing the body to overproduce aggression-related hormones. These hormones are present in the bodily fluids in sufficient quantities that contact with them can affect others. This is why people show symptoms so early. It's more like a drug taking effect.
The infected go into a state of hibernation when there are no uninfected humans around.If there's no one for them to infect, their metabolism drops to extremely low levels to conserve energy. This explains how they are able to survive so long without eating or drinking.
This movie is in the same universe as 28 Days.The stories don't cross, but the rage virus is released the same day that movie ends.
