Ben Affleck films a movie about filming a movie in “Argo,” recounting a daring CIA plot to save six American diplomats caught up in Iran’s Islamic revolution. The first trailer for the film was released today.

The movie is based on a true story that unfolded after Iranian Islamic radicals seized control of the U.S. Embassy in Tehran. Six diplomats escaped to the Canadian embassy, and a daring plot was hatched to free them.

The movie, which Affleck directs, also stars Bryan Cranston as Jack O’Donnell, Clea DuVall as Cora Lijek, John Goodman as John Chambers, Michael Parks as Jack Kirby and Taylor Schilling as Christine Mendez.

The screenplay is based on an article by Joshuah Bearman, “How the CIA Used a Fake Sci-Fi Flick to Rescue Americans from Tehran,” that appeared in 2007 in Wired magazine.

Affleck plays Tony Mendez a real life CIA technical operations officer who was involved in clandestine and covert CIA operations. He hatched the so-called “Canadian Caper” that led to the hostages’ freedom.

In the trailer, Mendez is shown hatching the plot to fly in and fly out with the diplomats posing as film crew members. He heads for Hollywood to gin up a fake sci-fi movie that requires a desert location to film.

The tense fast-paced film, appears to be leavened with just enough dry humor to provide some dramatic relief. “So you want to come to Hollywood and act like a big shot without actually doing anything,” says Goodman as John Chambers.

“Yeah,” says Mendez.

“You’ll fit right in,” Goodman replies.

Chambers is a legendary Hollywood makeup artist, who helped create the cover story that allowed Mendez to slip into Iran and make the rescue.

“Argo” debuts in theaters on Sept. 14. Check out the trailer below.
