Satoshi Kon's masterpiece which I believe to be one of the greatest films of all time.
Perfect Blue was originally intended to be a live action adaptation of Yoshikazu Takeuchi's novel of the same title, however a very infamous earthquake occurred in 1995 leaving the film studio in shambles. After that quake, the budget for a live action film adaptation was out of the question. In a way, I consider this unfortunate turn of events to be a blessing, because I can't picture this film any other way. This is a masterpiece of animation, and a disturbing one at that, what makes it so terrifying is it's realism in the way it portrays superstardom and obsessive fans, it's hard to explain further without spoiling anything, so just let me say this, you're in for a fucked up ride, and seeing this film in theaters was an unforgettable experience.
