Doppelganger

There are some elements of Hitchcock in the film. The set up is annoyingly slow for some people, but it's quite rewarding. The message of the film, is to listen to your own self, not the doppelganger. the doppelganger is within us, not necessarily seen. The point of him seeing is doppelganger, is that his double has the temerity to do the things he (Hayasaki) couldn't do. As he becomes bolder and more amoral he wonders is he becoming the doppelganger? Is Hayashi becoming the worst part of himself? Or perhaps his double is the real suppressed Hayashi? He discovers his ruthless, ambitious, lustful self through his double. It would make an interesting remake with issues of duality and existentialism. If we could have a conversation with ourselves, what would we say? - what would our other self say to us? This would be a fascinating concept that was done in several films - most notably "Jo Jo Dancer, Your life is Calling" - "the ghost of Christmas future showing Jimmy Stewart's future without him and his effect on others. Also "Family Man" with Nicolas Cage explored this theme. DePalma's "Raising Cain" (to a lesser degree) I thought this premise was pretty good - some may think it was a bit underdeveloped, but I liked it.
