Film choice

Brassed Off (Mark Herman, 2006), 11.05pm, Film4
Like The Full Monty, a story of northern folk facing industrial ruin. But while Monty is at heart a feelgood movie, this is bitterly angry, with laughter as light relief: the pits are on the verge of closure, a community is fragmenting, and Pete Postlethwaite’s Grimley Colliery Band plays on, even if it is the last post. Paul Howlett
