Ian Palmer's Knuckle created something of a sensation at Sundance with audiences walking out buzzing about the raw power of what they had just witnessed. A project twelve years in the making, Knuckle chronicles the seldom seen world of the Irish Traveller community and the underground fights staged for sport, entertainment, and grudge. In particular it tells the story of three rival clans who absolutely hate each other and their desire to work out their frustrations on each other's faces.

An epic 12-year journey into in the world of an Irish Traveller community, KNUCKLE takes us inside their brutal, secretive and exhilarating bare-knuckle fighting lives.

Chronicling a history of violent feuding between rival families, the story focuses on two brothers as they fight for their reputations and the honour of their family name.

Brutal, yet captivating and ultimately moving, this unforgettable documentary offers an exclusive insight into the world of Irish Travellers and the lengths they will go to protect their family name.

The film hits UK screens on August 5th - the documentary version will be coming to the US soon after and there is also a fictionalized version of the story in development - and the first trailer has just arrived. Check it below.
