Horses, Liz Mermin's "intensely strange" but bewitching documentary about a year in the life of a trio of Irish "horse athletes", has already been seen at the Sheffield Doc/Fest and at the ICA in London. Now, recut and retitled Race Horses, it comes to BBC Four's Storyville tonight (March 11) at 9pm. Read theartsdesk's interview with Liz Mermin here, and take a gallop with Joncol, Cuan na Grai and Ardalan.
