Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964)

Really really enjoyed this movie. The plot was engaging, the pacing was relatively constant, and the story was coherent. The performance by Peter Sellers, or the three performances, were all top notch; in fact the acting all around was great. The lighting of certain shots, set design, and certain camera angles will certainly stick with me. For it's use of primarily 3 locations, and a heavy reliance (and successful one at that) on dialogue, this movie would make a good double feature with 12 angry men. A sort of lighthearted cool down after the courthouse drama.
