The second brainstorm was the title of the film. I want to call the movie Pi . When the idea came to me it made so much sense. Plus it's a great marketing angle. Writing movies is like reverse paranoia.
Paranoids see signs of a hidden order behind reality.
When you write a movie you construct a world of signs which all point to the protagonist. The result is a fictional world which mirrors the world of paranoids. In fact, this may mean that Americans who spend hours in movies think that everything is going to work out and everything has an ordered purpose, like a Hollywood script. But the reality is that things don't work out and everything is chaotic. Hollywood films have turned America into a land of paranoids.
