One of two films that writer/director Paul Brickman wrote that was released by "Warner Bros." in 1983.

However, poor test screenings forced the studio to do a last minute re-write which involved the million dollar addition of comedy megastar Eddie Murphy "Strategetic Guest Star" character delayed the film from its intended Christmas 1983 release until summer 1984. This film also suffered from problems mostly due to the departure of writer Paul Brickman due to re-shoots on "Risky Business" and Chevy Chase's problematic ego on set.

Some scenes, involving helicopters and explosives, were shot at Indian Dunes Motorcycle Park in Valencia, California. This was the same location where, the year before, scenes involving a helicopter and explosions were being filmed for John Landis' segment for Twilight Zone: The Movie (1983). In that instance, tragedy struck, when the helicopter, hovering amidst explosions, had its tail rotor destroyed by the heat from the explosions, causing the chopper to spin out of control, and was sent spinning into a shallow river below, and killing Vic Morrow and two small children, who were attempting to cross the river at the time.
