Based on the 2012 phenomenon, its plot follows novelist Jackson Curtis (Cusack) and geologist Adrian Helmsley (Ejiofor) as they struggle to survive an eschatological sequence of events including earthquakes, volcanic eruptions, megatsunamis, and a global flood.

Filming, planned for Los Angeles, began in Vancouver in early August 2008 and wrapped up in mid-October 2008. The film ran a lengthy advertising campaign, which included the creation of a website from its main characters' point of view and a viral marketing website on which filmgoers could register for a lottery number to save them from the ensuing disaster.

Released in the United States by Sony Pictures Releasing on November 13, 2009, 2012 received mixed reviews, but was a commercial success, grossing $791.2 million worldwide against a production budget of $200 million, becoming the fifth highest-grossing film of 2009.
