Dèmoni 3: Black Demons (released on video as Demoni 3) is a 1991 Italian horror film directed by Umberto Lenzi (his last horror film).  It was written by Lenzi and his wife Olga Pehar, and the zombie makeup fx were handled by Franco Casagni.  Lenzi said in later interviews that this was one of his favorite films, but he felt it was ruined by the low budget and some of the shoddy actors he was forced to work with.  Lenzi intended the film to be called "Black Demons", and he did not like it when the film was later retitled "Demoni 3" on video, because some people thought it was part of Lamberto Bava's "Demons" series, which it had absolutely nothing to do with.

The title takes its name from a quote by Edgar Allan Poe, in which he refers to fear as a "knife of ice which penetrates the senses down to the depth of conscience."
