Background
Brian K. Vaughan is an American comic book writer. His series include Y: The Last Man, Ex Machina and Runaways. He also contributed an arc to writer Joss Whedon's comic book continuation of Buffy the Vampire Slayer and authored the graphic novel Pride of Baghdad. http://lostpedia.wikia.com/wiki/Brian_K._Vaughan
While still an undergraduate film student at New York University, Vaughan took part in The Stan-hattan Project, a joint venture between the school's Dramatic Writing Department and Marvel Comics aimed at developing new talent for the publisher.
In addition to his own original work, Vaughan has written for major characters in both the DC and Marvel Universes including Batman and the X-Men. http://theplaylist.blogspot.com/2010/03/brian-k-vaughan-entering-vault.html
With respect to film and television, Vaughan joined the writing staff of ABC television series Lost in the show's third season. Both Y: The Last Man and Ex Machina are being adapted for the screen, though they are currently being stalled in production, without a clear release date or conclusion to shooting and theatrical budget.http://www.imdb.com/name/nm1592205/
Departure from Lost
Vaughan left Lost in July of 2009, just prior to the last season of the iconic ABC prime-time series. Executive Producer Damon Lindeldorf announced that he had "left for greener pastures." http://splashpage.mtv.com/2009/07/06/brian-k-vaughan-leaves-lost-writing-staff/ Vaughan was known for contributing a heightened a wareness of pop culture to the show, including references to comic book superheroes and his own works, which often manifested in the dialogue and interactions of its characters. The character of Hurley, for instance, was shown in one episode to be reading a foreign version of Vaughan's comic Y: The Last Man in an airport. Jorge Garcia, who plays Hurley, was in fact a big fan of Vaughan's work. http://splashpage.mtv.com/2009/07/06/brian-k-vaughan-leaves-lost-writing-staff/The series certainly benefited from the comic book master's fanbase, especially given the convoluted and oft-confusing nature of the show, which relied on conspiracy theories and fan hypotheses.
The Vault
Though Vaughan certainly gained a great deal of popularity and exposure as a writer for the acclaimed Lost TV series, when he left the show as of last summer, speculation was rampant as to what his next project would entail. This was especially the case since Ex Machina is due to wrap up soon. All the anticipation and excitement boiled over when, on March 25h, 2010, Vaughan's representatives reportedly revealed a script that he had been working on, entitled The Vault. http://www.slashfilm.com/2010/03/24/early-buzz-brian-k-vaughans-post-apocalyptic-heist-screenplay-the-vault-is-oceans-11-meets-2012/The movie setting takes place in the middle of the Arctic, where a real-life "doomsday vault" is located. The real-life vault is named the Svalbard Global Seed Vault, and it contains a variety of plant seeds 800 miles from the North Pole. The thinking behind the vault is to provide a way for humans to sustain themselves after a catastrophe wipes out crops.http://www.slashfilm.com/2010/03/24/early-buzz-brian-k-vaughans-post-apocalyptic-heist-screenplay-the-vault-is-oceans-11-meets-2012/
In Vaughan's version, set in a post-apocalyptic environment, "a terrifying plague destroys crops and causes starvation on a global scale," and "the world’s greatest thief must break into the extremist-controlled Doomsday Vault to steal the one seed that could prevent the extinction of the human race" http://www.slashfilm.com/2010/03/24/early-buzz-brian-k-vaughans-post-apocalyptic-heist-screenplay-the-vault-is-oceans-11-meets-2012/ The vestiges of mankind are forced to break into the vault, which is guarded by "extremists". SlashFilm describes the film idea as a fusion of Ocean's Eleven, with its heist-oriented action, and the post-apocalyptic science fiction thrillers Children of Man and 2012]. It should be noted that a number of Vaughan's comics and graphic novels were reportedly due to be made into movies, but they have since been placed on theatrical hiatus. With Vaughan's reps actively shopping around his script, it may one of his first to become a full length motion picture.http://theplaylist.blogspot.com/2010/03/brian-k-vaughan-entering-vault.html
Interview with Brian K Vaughan
This shows an interview by Geekscape in October of 2008 where Brian K Vaughan took questions regarding his acclaimed series Y: The Last Man, along with his other projects that he was working on at the time, such as his involvement with the Lost TV series. Although the "Last Man" was meant to be adapted into a movie, supposedly with Shia LaBoeuf, the project has stalled, and Vaughan has since pushed ahead with The Vault instead.
