Panic in Year Zero!, sometimes known as End of the World, is a 1962 science fiction film directed by and starring Ray Milland. The original music score was composed by Les Baxter. Soon after Harry Baldwin (Ray Milland), his wife Ann (Jean Hagen), their son Rick (Frankie Avalon), and daughter Karen (Mary Mitchell) leave suburban Los Angeles on a camping trip, the Baldwins note unusually bright light flashes coming from a great distance. Sporadic news reports on CONELRAD broadcasts hint at the start of a thermonuclear war, which is confirmed as the Baldwins see a large mushroom cloud over what was Los Angeles. The family initially attempts to return to rescue Ann's mother near Los Angeles, but soon abandons these plans as panicked refugees climb over one another to escape the fallout from the multiple nuclear explosions.
