Dario Argento's World of Horror

Il Mondo dell'orrore di Dario Argento (Dario Argento's World of Horror) is an 1985 Italian documentary film, which chronicles the career of the Italian horror and suspense movie director, Dario Argento. It was the directorial debut of Michele Soavi, who later went on to direct the cult classic Dellamorte Dellamore in 1994.

The documentary features candid interviews with Argento and various stars from films he has directed, as well as extensive clips and behind-the-scenes footage of his films. The film includes segments focused on subjects as the soundtrack work, coloring and color filtering, and camerawork in Suspiria, the soundtrack for Inferno, the camerawork and insect effects in Phenomena, Tom Savini's make-up work in Dawn of the Dead, and the special effects, make-up and robotics in Dèmoni as well as interviews with Argento on a variety of esoteric subjects. Because most of Argento's films were only available at the time in heavily edited form, Dario Argento's World of Horror was sought after by many fans of the director's work because it contained numerous clips of footage removed from the released films, most notably the opening double murder sequence from Suspiria.
