Trivia, insights & behind the scenes
Based on the real 1993 Saitama dog-lover murders, where a married couple killed at least four people. Sono shifts the setting to a fish store to explore Japanese masculine anxieties around small-business failure.
The film's Japanese title 'Tsumetai Nettaigyo' (Cold Tropical Fish) references how tropical fish die when water temperature drops — a metaphor for passionless marriages and the 'coldness' required to survive capitalism's demands.
