The 1983 film War Games targeted a teen demographic, but was well-reviewed as a thriller for general audiences. The film captured the zeitgeist of the US completely: nearly half of the country (100 million TV viewers) had just lived through the airing of the The Day After, a film about the dire consequences of nuclear war. From a review by the renowned film critic Roger Ebert: "Sooner or later, one of these self-satisfied, sublimely confident thinking machines is going to blow us all off the face of the planet. That is the message of War Games, a scary and intelligent new thriller ... The movie stars Matthew Broderick as David, a bright high school senior who spends a lot of time locked in his bedroom with his home computer. He speaks computerese well enough to dial by telephone into the computer at his school and change his grades. But he's ready for bigger game."

David interacts with a supercomputer which just happens to belong to the United States Department of Defense; he unwillingly triggers it to play a "game" which leads DoD personnel to think that an actual nuclear attack on the US is underway. MovieThemeSong.com explains that the supercomputer "begins simulating endless nuclear war scenarios, every one ending with the result "WINNER: NONE." Eventually (it) comes to the film's famous conclusion about nuclear war: The only winning move is not to play."

The film's score, written by busy film/TV composer Arthur B. Rubinstein (not to be confused with the noted classical pianist), included an instrumental closing credit entitled "Edge of the World." This shorter version features vocalist Yvonne Elliman, perhaps most known for "If I Can't Have You" from the Saturday Night Fever soundtrack (1977). The video features scenes of the nascent romance between David and Jennifer (Ally Sheedy), complicated by the very real risk that their world might soon disappear.
