If you loved The Bird with the Crystal Plumage, try Opera
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
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 The Bird with the Crystal Plumage, the second film will land in a comparable space — through a different lens.

What Opera is
Parma. Winter. A raven's shriek. Betty replaces a diva in Verdi's Macbeth, bringing a masked killer from the shadows. Each performance brings a fresh kill, each kill brings Betty closer to center stage. Argento at his most meta and self-lacerating.
