The Wind that Shakes the Barley

Ken Loach has a hit on his hands with a film about the Irish Struggle for Independence centring on the fight against the 'Black and Tans'. This is a great period for films - it was visited in the big-budget Michael Collins.
Loach's historical film Land and Freedom was certainly very good so this bodes well.

Stills like the one on the left here
The title is an old Irish song.
