You wait and wait for a movie about a mathematical genius, and then three come at once. I’ve got Turing, I’ve got Ramanujan, I’ve got Erdős.

### The Imitation Game

*The Imitation Game* is an Alan Turing biopic, starring Benedict Cumberbatch and Keira Knightley. It’s out in November, but this trailer has just been released.

### The Man Who Knew Infinity

*The Man Who Knew Infinity* is a Srinivasa Ramanujan biopic, starring Dev Patel and Jeremy Irons and based on Robert Kanigel’s book. It’s been in development hell for eight years, but according to *Variety* filming will start in Cambridge in August.

### Erdős-Bacon

*Erdős-Bacon* is a documentary about the Small World Phenomenon, and in particular the quest to minimise both your Erdős number – the number of publications linked by co-authors between you and Paul Erdős – and your Bacon number – the number of films linked by cast members between you and Kevin Bacon.

The producers are a keen and youthful bunch, which means they’ve gone to Kickstarter to raise money. They want \$40,000, and they hope this pitch will encourage you to open your wallets:

This documentary is the handshake that links a famed actor and a legendary mathematician, creating history’s lowest Erdős-Bacon number.

Slate also has a story on the Turing biopic. I didn’t feel like its criticism that the trailer hides his sexuality is fair. I mean, it’s only a 2-minute trailer, and I think it’s pretty clearly alluded to. And he was engaged to her for a time, so their relationship is not completely fabricated. What do you think?
