Pânico no Ano Zero

Shot in nice moody black-and-white CinemaScope, starring Ray Milland, Jean Hagen (a far cry from Lina Lamont here!), and Frankie Avalon getting the chance to do a serious role. Interestingly it was also directed by Ray Milland, and is a fairly accomplished little cinematic parable, again dealing with the threat, and here the after-effects, of atomic warfare.

Milland and his family set off on a weekend camping/fishing trip and a flash in the distance they think at first is lightning turns out to be an atomic mushroom cloud over Los Angeles. The rest of the film they attempt to survive and maintain some resemblance of civilized behavior while rationalizing their lapses into violence against the panic-stricken populace, looters, and opportunists who suddenly appear. It might easily have been handled as the exploitation film promised by the trailer (it's an American International production, after all), but is actually a very thoughtful and well-structured meditation on how people might react in the event of the massive nuclear attack everyone was fearing at the time.
