Pi (1998)

Darren Aronofsky's first film. A number theorist with migraines finds a 216-digit string in the market data; a group of Hasidim recognise it as the Shem HaMephorash, the unspeakable name, and want it for the Messianic age.

⭐⭐ THE ONE FILM THAT PUTS GEMATRIA IN THE MACHINE. It gets the practice roughly right — the Torah as a string of numbers, the name as a computable object — and then asks the question the tradition asks about itself: what happens to the person who actually finds it. Made for $60,000 in black and white.
