This has gotta rate as one of the all-time greatest fright films. Italian horrormeister Dario Argento outdid himself with this surrealistic 1977 shocker. Jessica Harper is an American dancer who goes to a fancy European ballet academy and uncovers a murderous cabal of witches. The film doesn't make much logical sense, but it hits you like a ton of nightmare bricks. The glaring colors and screaming soundtrack will haunt you for weeks!98 minutes R.
