Pi (movie)π (pronounced, and often written as, Pi) is a 1998 American science fiction film directed by Darren Aronofsky. The film is about an aloof genius who believes that mathematics is the language of nature, and pursues the fundamental formula for it. He finds the golden spiral occurring everywhere, including in an analysis of the stock exchange which he is carrying out. A number of mysterious people become interested in his research, including a Go-playing mathematician who seems his mentor, a woman from a Wall Street firm with access to powerful new computer hardware, and a group of kabbalistic Jews who believe that the Torah, when represented as numbers instead of letters, is the true name of God.
π had an extremely low budget ($60,000), and made huge profits ($3.2 million gross in the U.S.). Darren Aronofsky made the movie Requiem for a Dream after π.
π launched the film scoring career of Clint Mansell.
