Deal of the Century is a 1983 American comedy film directed by William Friedkin and starring Chevy Chase, Gregory Hines, and Sigourney Weaver.

Hobbling in a rundown hotel days later, Muntz meets Harold DeVoto, a sales rep for the American defense contractor, Luckup.

Muntz peddles small arms (assault rifles, anti-personnel mines, and machine-pistols disguised as cassette tape players), whereas Luckup's product is more sophisticated—the Peacemaker UAV, a military dream that operates without pilots or airbases.

Waking up in the hospital, Muntz is told by Frank Stryker, a Luckup executive, that San Miguel reneged on the deal after a disastrous and highly publicized demonstration of the Peacemaker.

Muntz's efforts are complicated by tensions with Luckup, Ray's religious conversion, "The Peacemaker's" many technical glitches, and his own growing moral reservations.

On the eve of a major defense industry exposition, Muntz is visited by Massagi, an immensely wealthy arms merchant who both encourages him to finalize the San Miguel deal and coaches him on how to do it.

Massagi reveals that the global arms industry has a stake in sales of weapons like the Peacemaker because they allow for localized and conventional wars that will keep their business viable into the next century.
