"Zero Dark Thirty" is military terminology for 30 minutes after midnight (in military time, it would be expressed as 00:30), and it is also slang for any time between 12 a.m. and sunrise. Director Kathryn Bigelow said that it also referred to "the darkness and secrecy that cloaked the entire decade-long mission." The working title of the film was "For God and Country," and the original plan was to tell the story of bin Laden's escape from American forces in Tora Bora in 2001.
