The script for fake CIA movie Argo was actually from an unmade adaptation of Roger Zelazny's sci-fi novel Lord of Light. This artifact and others from the elaborate cover story cooked up by the spy agency can be seen in a new exhibit in New York. The film's concept art, made when it was still an adaptation of Lord of Light, was created by famed comic book artist Jack Kirby. Studio Six even made their own letterhead and business cards. Artist concept drawings for the "Argo" film show a Middle Eastern sci-fi theme. The production notes for the flick included an introduction letter, locations, story treatments and other visual items. The fake film the CIA invented took its name from the vessel Jason used to retrieve the Golden Fleece, so the movie was supposed to have a futuristic look. As part of the cover, ads for the film were taken out in trade publications like Variety. Intricate concept art was intended to help make the ruse Studio Six was trying to pull off more believable.

Before Argo became a suspenseful Ben Affleck-directed film, it was a story in Wired. But long before that, it was known as the “Canadian Caper” — a rescue mission coordinated by the CIA and the Canadian government to rescue six U.S. diplomats from Iran, using a nonexistent sci-fi flick as cover.

“It was an incredibly audacious operation,” spy historian H. Keith Melton, co-author of The Official CIA Manual of Trickery and Deception and owner of many items on display in a new exhibit of Argo artifacts, said in an interview with Wired. “The key was the film, so they had to take a viable premise and it had to have a real script, it had to have offices, it had to have a poster, it had to have people assigned to it, it had to have people to answer phones…. These artifacts were the original pieces that were created for it.”

The declassified materials used by the CIA in its elaborate covert op are now on display at New York’s Discovery Times Square as part of Spy: The Secret World of Espionage. (See a few select items in the gallery above.)

The pieces on display, which range from legit-looking office supplies to historical concept art by famed comic book artist Jack Kirby, show just how deep the CIA’s cover was for the operation.

The plan was that CIA “master of disguise” Tony Mendez (played by Affleck in the film) would go into Iran, find the six diplomats, and get them out of the country by pretending they were all part of the Argo production crew. As part of the operation, Mendez worked with Hollywood makeup artist John Chambers (played by John Goodman) to help set up the fake studio and its faux film Argo, complete with ads and stories in the trades.

The Agency’s fake production studio served as a convincing front as the spies worked to extract the half-dozen Americans who had gone into hiding in 1979 after militant students raided the U.S. embassy in Tehran during the Iranian Revolution.

Check out some of the items on display — none of which had been seen prior to the Spy exhibit — in the gallery above. The exhibit runs through March 2013. Affleck’s Argo opens Friday.
