Tombs of the Blind Dead

The best thing Spanish horror produced, and it comes down to a single design. Executed Templar knights rise from a ruined monastery: eyeless, mummified, hunting by sound, and riding skeletal horses in extreme slow motion. It should be silly. It is frightening.

Amando de Ossorio insisted they were not zombies, which is technically true and beside the point. The film around them is standard, the Blind Dead themselves are not, and they carried three sequels.

Watch it for the slow-motion horseback attack, which nobody has bettered.
