Perfect Blue (Japanese: パーフェクトブルー, Hepburn: Pāfekuto Burū) is a 1997 Japanese animated psychological thriller film directed by Satoshi Kon. It is loosely based on the novel Perfect Blue: Complete Metamorphosis (パーフェクトブルー：完全変態, Pāfekuto Burū: Kanzen Hentai) by Yoshikazu Takeuchi, with a screenplay by Sadayuki Murai. Featuring the voices of Junko Iwao, Rica Matsumoto, Shiho Niiyama, Masaaki Okura, Shinpachi Tsuji and Emiko Furukawa, the plot follows a member of a Japanese idol group who retires from music to pursue an acting career. As she becomes a victim of stalking by her obsessive fan, gruesome murders take place, and she begins losing her grip on reality. The film deals with the blurring of the line between fantasy and reality, a commonly found theme in Kon's other works, such as Millennium Actress (2001) and Paprika (2006).
