@Andres: Darren Aronoffski directed a movie called "Pi", it's really bad in terms of mathematics and some overacting in some parts. Nice few lines out of it, though. –  Asaf Karagila May 3 '11 at 18:59
    
Asaf: Yes, I know. There are also movies called "The number 23" and "I am number four." –  Andres Caicedo May 3 '11 at 19:23
