If you loved Terreur à l'opéra, try L'Oiseau au plumage de cristal
Un pont entre un film que tu as déjà vu et un que peu de gens ont croisé. Voici ce qu'ils partagent, et ce que le second fait que le premier ne fait pas.
Ce qu'ils partagent
Both films are directed by Dario Argento, and they both carry the dread mood tag, and they sit in Horror / Mystery / Thriller territory. If that's the register that drew you to Terreur à l'opéra, the second film will land in a comparable space — through a different lens.

What L'Oiseau au plumage de cristal is
Rome. Wet streets, late at night. The shriek of a woman. Sam Dalmas, an expatriate novelist, sees a shadowy figure attacking a woman in an art gallery, but he's trapped between glass doors. The killer, masked, begins hunting him. Argento's debut refines giallo conventions.
