Pi Trailer (1998)

The film is about a mathematical genius, Maximillian Cohen, who narrates much of the movie. Max, a number theorist, theorizes that everything in nature can be understood through numbers, and that if you graph the numbers properly patterns will emerge. He is working on finding patterns within the stock market, using its billions upon billions of variables as his data set with the assistance of his homemade supercomputer, Euclid.
