2. 'La Jetée' (1962)
A gorgeous 28-minute film, told in a montage of black-and-white still photographs and narrated in French, about a man sent back in time to avert an apocalyptic war. He's obsessed with his childhood memories of a beautiful woman and seeing a man die — inevitably, he gets tangled in the silken cords of time travel. This novella of a movie is pretty much perfect, which didn't stop Hollywood from making a big-budget feature-length version: 12 Monkeys (1995), directed by Terry Gilliam, and starring Bruce Willis and Brad Pitt.
