Deep Dive

Trivia, insights & behind the scenes

Cultural

1970s Korean cinema often used female protagonists to critique patriarchal structures while punishing them narratively—a contradictory tension this film embodies.

Trivia

Director Lee Man-hee died at 43, leaving 50+ films; this late-period thriller reflects his commercial pivot after government censorship eased.
