La Jetee is a 28-minute French film composed almost completely from still black and white photos. It was directed by Chris Marker in 1962, and inspired Terry Gilliam's 12 Monkeys. The main character of the film is held prisoner and subjected to time travel experimentation, where he essentially realizes that a death he witnessed as a child was actually his own death. I am in awe of how such a brilliant short film can result from still photos.
This is absolutely my favorite film of all time. There is a scene where the woman is on the bed and the photographs are put together so well that you would swear there is just a moment of video. Stunning.
