Syriana is a 2005 geopolitical thriller film written and directed by Stephen Gaghan, and executive produced by George Clooney, who also stars in the film with an ensemble cast. Gaghan's screenplay is loosely adapted from Robert Baer's memoir See No Evil. The film focuses on petroleum politics, and the global influence of the oil industry, whose political, economic, legal, and social effects are experienced by a CIA operative (George Clooney), an energy analyst (Matt Damon), a Washington attorney (Jeffrey Wright), and a young unemployed Pakistani migrant worker (Mazhar Munir) in an Arab country in the Persian Gulf.

As with Gaghan's screenplay for Traffic, Syriana uses multiple, parallel storylines, jumping from locations in Texas, Washington D.C., Switzerland, Spain, and the Middle East.

Clooney won the Academy Award for Best Supporting Actor for his role as Agent Bob Barnes, and Gaghan's script was nominated by the Academy for Best Original Screenplay. As of April 20, 2006, the film grossed a total of $50.82 million in the U.S. box office and $42.9 million in the rest of the world, for a total of $93.73 million.
