Five things you need to know:
1. Barbaric Genius is a documentary about London-Irish author, chessmaster and troubled soul John Healy, author of The Grass Arena, a seminal autobiography that you need to track down immediately. Now, that’s what we call a summer read.
2. Venerable thespian Mark Rylance played Healy in the BBC version of The Grass Arena.
3. A truncated take on Barbaric Genius ran on RTE a few months back – this is the feature length version. It’s better. In fact, it’s the best Irish documentary of 2012.
5. Barbaric Genius opens at the IFI Dublin today.
