The Devil's Nightmare

La Plus Longue Nuit du Diable

1971 ·1h 35m · ★ 6.1 (47)

Seven tourists sent by Satan to a castle are caught by a ghastly woman as they commit deadly sins.

Why it matters

A moody Euro-Gothic chamber piece where sin literally seals your fate in a shadow-drenched castle.

  • Early ’70s Euro horror that blends giallo’s moralistic edge with Gothic atmosphere—think ritualistic dread over cheap scares.
  • A succubus femme fatale delivers a slow-burning, symbolic reckoning for each of the seven deadly sins—pride, lust, envy, and all.
  • Authentic castle setting and period detail ground the supernatural in tangible dread, elevating the eerie ambiance.
  • For fans of Euro folk horror and occult morality plays who appreciate horror’s reflective gaze on human vice, despite some pacing that lingers too long.
