Some famous ones I enjoyed are 'Dr Strangelove', 'WarGames', and 'The Day After'.
I also enjoyed the lesser-known 'Miracle Mile' and 'Matinee (1993)'.
Haven't seen 'On the Beach', but it's an early (1959) well-reviewed film on the topic. Haven't seen 'Thirteen Days', but it covers the Cuban missile crisis -- perhaps the closest the world came to using nuclear weapons after Hiroshima and Nagasaki.
