The Keep

The Keep (1983) is Michael Mann's supernatural horror film you can watch online on iFILM. The Carpathian mountains, Romania, 1941: a Wehrmacht detachment moves into a massive ancient fortress to hold a mountain pass. Scott Glenn, Jürgen Prochnow, Gabriel Byrne and Ian McKellen head the cast.

Two soldiers pry open a sealed chamber inside the fortress walls. What gets out has been locked in by generations of local guardians. It starts killing — methodically, nightly. An SS unit arrives, convinced local partisans are responsible, and takes villagers hostage. The fortress does not care. A Jewish historian brought in under armed escort to read the inscriptions on the walls begins to suspect the entity is not hunting victims at all; it is waiting for someone to set it free.

Mann shot The Keep between Thief and Manhunter. Cinematographer Alex Thomson's fogbound visuals and Tangerine Dream's synthesizer score give the film an atmosphere that outlasts its runtime. Watch The Keep (1983) online on iFILM.
