Helicopter chase scene (Twilight Zone: The Movie, 1983)
Sci-fi horror anthology film Twilight Zone features four stories and director John Landis’ segment, titled Time Out, stars Vic Morrow as Bill Connor, a man who becomes unstuck in time, landing in various episodes of the past. An outdoor set in California doubled as one of Bill’s destinations, the Vietnam War.
Filming went well until the last day when shooting called for Morrow to be chased by a helicopter for a scene. The chopper lost control after a special effect damaged it. It then crashed into Morrow and two child extras, subsequently killing them all. The footage of their deaths was destroyed, and a lengthy legal battle over fault ensued.
