Gah.
Kubrick is my all time favourite director, making me choose is so hard
Equal tossup between Full Metal Jacket and Dr Strangelove, because I find both to be comedies... well FMJ at times isn't at other times it's just downright funny...
No Strangelove takes it for today. Especially how the same actor plays Dr Strangelove, the President and Mandrake.
