Most visually stunning films: Deep Red (1975), Suspiria (1977), Inferno (1980)

To best enjoy the work of Italian horror master Dario Argento, one must adhere to what’s commonly referred to as “nightmare logic.” Which, for those who’ve yet to succumb to Suspiria’s hallucinogenic force, is the voluntary dismissal of such things as coherent plotting and the making of sense in favor of random atrocities presented in the director’s obscenely bright colors and operatic energy.

In Argento’s craziest films, namely the aforementioned Suspiria (one of the last movies ever processed in lush Technicolor) and it’s quasi-sequel Inferno, scenes of frantic brutality are heightened by exaggerated palettes, such as the stark blue background and red flashes that back Suspiria’s classic opening murder. When the blood flows in an Argento movie, it doesn’t just ooze out in putrid rivers—it glistens like ocean water beneath a shining sun.
