A German ballet school for girls is the setting for mysterious deaths, in this 1977 horror story, written and directed by Dario Argento. "Suspiria" is a visually stunning film. The images contain objects we recognize, like people, buildings, and interior decor. But the objects seem vaguely menacing, and less real than surreal, as though they symbolize ideas, repressed desires, or subconscious fears. The vivid, rich colors, strange camera angles, deep shadows, and bright light piercing through darkness, all contribute to the impression that the viewer is trapped in someone else's nightmare.
If you are looking for a trippy halloween flick you could do worse then Suspiria. Sampled by Ministry! What more could you ask for?
For something a bit more surreal I might also offer that you check out the works of Jan Svankmajer. Teaser here.
