"Mendez said he needed a movie script for a scheme that he had concocted to rescue six U.S. diplomatic personnel from the Canadian embassy in Iran where they were hiding. The agent had planned to travel to Iran under the guise of a movie producer and fool Iranian officials into believing that the six Americans were actors and members of his production team. Fortunately for Mendez, Chambers had the perfect script. In December 1979, Chambers gave Mendez Geller's Lord of Light script and Kirby's storyboards, which had remained in Chambers' possession since the plug was pulled on the film's production. Chambers and Mendez changed the name of the production from Lord of Light to Argo and the rest of the story became history, as the plan was successful and all six Americans made it home safely. Geller said he didn't learn that his script had been used for the top secret mission until 2001."
