Decay, the movie, seems to have been released in late November 2012.  It is, according to the Nov. 1, 2012 preview article written by Rebecca Pahle for The Mary Sue website, a project developed by physics students working at CERN’s (European Particle Physics Laboratory) Large Hadron Collider facility.

There are a lot of zombie movies out there. But Decay is the only one filmed in CERN, a.k.a. the home of the Large Hadron Collider. The film is the brainchild (mmmm… brains) of Luke Thompson and Clara Nellist, both Ph.D. students in physics, who despite having no filmmaking experience decided that, dammit, they were going to make a film about exposure to the Higgs Boson particle turning people into zombies. (If that sounds critical, it’s unintentional—jumping in and just doing it is a time-honored method for indie film.)

Though Thompson and Nellist got permission to shoot their film in CERN, the just-released trailer makes it very clear that officials there in no way endorse it. (Which—of course they wouldn’t. But they let them shoot there! How cool is that?)

Here’s the movie trailer,

J. Bryan Lowder’s Dec. 12, 2012 article for Slate describes some of Lowder’s experiences as a science writing intern dealing with myths about science and the filmmaking team’s motivations (laughing at science horror myths),

Back when I was a science writing intern at a major U.S. lab, there was a short list of words we were cautioned never to use in our public articles. Radiation was at the top of that list, not because the lab produced it in dangerous amounts (actually, it produced less than exists normally in nature), but because when people read the word, they freak out. The public’s fear—and by extension, this lab’s fear of talking about—radiation is understandable, but it’s also unreasonable and reveals a disappointing ignorance of science. …

Burton DeWilde, a physics Ph.D. and Decay’s director of photography/editor (and a friend of mine), explained the genesis of the project in an email:

The idea of filming a zombie movie at CERN was originally conceived by Luke Thompson (writer-director) and Hugo Day (props master) while exploring the lab’s creepy labyrinth of underground maintenance tunnels. It was agreed that they would make an excellent setting for a horror film. From there, the story evolved into a cheeky riff on the black hole hysteria: “The LHC didn’t produce earth-devouring black holes after all—but have you considered brain-devouring zombies?” Concerns about the Higgs in particular and clichés of mad scientists were also mixed in. We took all these worries to a totally ridiculous place.

And Decay is totally ridiculous, in the best sense of the word. The 75-min, $3,500 movie is remarkably well-made, given the creative team’s lack of experience. It’s studded with all the gratuitous gore, cheap shocks, and absurd plot twists that zombie fans crave. Science nerds and those who love them will bask in its shameless use of sci-fi clichés like “the results are inconclusive at best,” and “my research is too important!”

Zombies are a very hot topic in popular culture these days as per this Nov. 12, 2012 posting on this website which mentions my presentation ‘Zombies, brains, collapsing boundaries, and entanglements’ at the S.NET 2012 (Society for the Study of Nanoscience and Emerging Technologies) conference in Enschede, Holland.

BTW, Mary Sue is a term used to describe a female character who is perfect. From the Urban Dictionary definition,

1. A female character who is so perfect that she is annoying. The name originated in a very short Star Trek story that mocked the sort of female characters who showed up in fanfiction. It usually refers to original female characters put into fanfiction, but can refer to any character. …
2. An original character (fem.) in fanfic or an original story, usually on the internet, who is far superior to all other characters. She is typically beautiful, intelligent, kind, and in all other ways “perfect”. She usually serves as an important part in a pivotal plot element (ie: a prophecy) and becomes romantically involved with the author’s favourite character in the story. The internet fiction world runs rampant with these characters. …

Do go to the Urban Dictionary to reed the examples of ‘Mary Sue’ characters as they are very funny. The male equivalent may be called Marty Stu, Gary Stu, or Marty Sam.
