Suspiria is a 1977 Italian supernatural horror film directed by Dario Argento, who co-wrote the screenplay with Daria Nicolodi, partially based on Thomas De Quincey's 1845 essay Suspiria de Profundis.

The 1977 version is much more straight-forward, with a shorter running time at only 99 minutes, as opposed to the 2024 adaptation at 152 minutes. The storyline flows and makes sense cohesively, with a gradual build to a terrifying climax.
