Spies Like Us 1985

Two bumbling government employees think they are U.S. spies, only to discover that they are actually decoys for Nuclear War.

Two low-level government employees, Emmitt Fitz-Hume (played by Chevy Chase) and Austin Milbarge (Dan Aykroyd), are chosen for a top-secret CIA mission. They are unsuitable as CIA agents but are deliberately chosen for this reason, as their mission is a decoy one and they are expendable. After being fast-tracked through training they are parachuted into Pakistan where all manner of adventures await them
