A general loses his mind and sets into motion a chain of events that could potentially start a nuclear war whilst a group of politicians and military try and stop such an event in the war room.
One of those films that is so well known and loved that even if you have never seen it you will find yourself knowing many of the lines anyway. I found George C. Scott as Buck and Peter Sellers as Mandrake to be the most hilarious of the all the characters but take your pick. They are all uniquely brilliant in their own way. Another Kubrick classic.
