Movies: Pi

This one is not as well known as some of the others in my classics list, but it is a true nerd cult classic for a few reasons:

1. It is an early film directed by Darren Aronofsky, of Black Swan fame
2. It is a FILM ABOUT MATHS - specifically about the Golden Ratio, and how it appears in nature and everywhere (trust me, once you have watched this, you will want to find out more! Its an amazing phenomona)
3. It's soundtrack was done by awesome electronic artists in the 90s including Roni Size and Aphex Twin
4. A central theme is the game "Go" which is heavily in the news at the moment, as Google's AI AlphaGo has beaten Lee Se-dol three games in a row
