Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb, 1964 - ★★★★
I'm sorry I haven't watched this sooner. A masterful Satire, frighteningly still related today almost as it was in the 1960s. This movie should go on the "need to watch" list of those who, unfortunately, will never watch it or will miss the message altogether.
The drumroll of the bomb run is so catchy I've made a phone ring out of it, hopefully to be listened to by other passengers on a subway car one day as a reminder.
