Perfect Blue (Japanese: パーフェクトブルー, Hepburn: Pāfekuto Burū) is a 1997 Japanese animepsychological thriller film[5][6] directed by Satoshi Kon.[7] 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.[8] 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).[9]
