Perfect Blue (1998)

Satoshi Kon's debut feature follows Mima, a pop idol who quits singing to become an actress, while fans insist that the "real Mima" is the singer they paid for. One of them runs a website called Mima's Room, a diary written as if by Mima herself, and the film turns that idea into a nightmare about someone else taking over your identity online. It first screened at the Fantasia festival in 1997, when most people had barely been online, and now reads less like a period piece than a forecast of internet celebrity. It is animated but strictly for adults, with violent and disturbing scenes, and its blurring of performance and reality went on to influence filmmakers such as Darren Aronofsky.
