Zero Dark Thirty is a 2012 American historical drama film directed by Kathryn Bigelow and written by Mark Boal. Billed as "the story of history's greatest manhunt for the world's most dangerous man," the film is a dramatization of the United States operation that found and killed Osama bin Laden, leader of al-Qaeda. It was produced by Boal, Bigelow, and Megan Ellison.

It stars Jessica Chastain, Jason Clarke, Joel Edgerton, Chris Pratt, Jennifer Ehle, Mark Strong, Kyle Chandler, and édgar Ramírez. It was independently financed by Ellison's Annapurna Pictures. The film had its premiere in Los Angeles, California on December 19, 2012 and had its wide release on January 11, 2013.
Zero Dark Thirty received wide critical acclaim and was nominated for five Academy Awards for the 85th Academy Awards, including Best Picture, Best Actress (Jessica Chastain) and Best Original Screenplay. Zero Dark Thirty earned four Golden Globe Award nominations, including Best Picture – Drama, Best Director, and Best Actress – Drama for Chastain.

It has also generated controversy, both for graphic portrayal of torture of suspects?and for what is described by some as a misleading portrayal of torture as critical to the United States' success in gaining information on bin Laden's associates and location. In addition, Republicans suggested that the filmmakers were given improper access to classified materials, which they and the Obama administration denied.
