If you loved Wolf Guy, try A Haunted Turkish Bathhouse
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 Kazuhiko Yamaguchi, and they sit in Crime / Horror territory. If that's the register that drew you to Wolf Guy, the second film will land in a comparable space — through a different lens.
What A Haunted Turkish Bathhouse is
Istanbul. Winter light on wet tile. A bathhouse madam and a yakuza's wife conspire. The target is his own spouse, a woman working downstairs. Betrayal steams and festers. A pinku-eiga detour into giallo-esque suspense.
