Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964) - 8/10
Of the four Stanley Kubrick movies I've watched so far (the others being Clockwork Orange, 2001 and The Shining), this is my favorite. It's hilarious, it has great characters, and the overacting Kubrick loves works well here. It shows how the world could easily end if a few of the right people were a bit stranger.
