I had a feeling you would really like this one! It has a lot of giallo influences as well -- Allen in her black lace undies, plus being stalked by a relentless killer in sunglasses and black leather gloves!

I saw Obsession (1976) on tv in the late 70s, years before I saw Vertigo, so I had no idea at the time that I was watching a cock-eyed Hitchcock reboot.
