Italian horror master Dario Argento elevates the giallo genre to new heights with 1982's TENEBRAE, a darkly humorous and notoriously grisly murder-mystery that many consider to be one of his finest works. American mystery author Peter Neal (Anthony Franciosa, Death Wish II) comes to Rome to promote his newest novel, Tenebrae. A razor-wielding psychopath is on the loose, taunting Neal and murdering those around him in gruesome fashion just like the character in his novel. As the mystery surrounding the killings spirals out of control, Neal investigates the crimes on his own, leading to a mind-bending, genre-twisting conclusion that will leave you breathless! Co-starring John Saxon (A Nightmare on Elm Street), Daria Nicolodi (Phenomena), John Steiner (Caligula) and featuring beautiful cinematography by Luciano Tovoli (Suspiria), this stunning 4K UHD (2160p)/Blu-ray (1080p) combo set includes hours of extras.
