Ian Palmers’ documentary about bare knuckle fighting in the Irish Traveller community caused a stir when it launched at Sundance earlier this year.

Content holds foreign sales rights to the story about two brothers who they fight for their families’ honour. Revolver will release in the UK on Aug 5. HBO acquired remake rights in Sundance.

Barry Gordon negotiated for ARC and XLrator with CAA on behalf of the filmmakers.

Knuckle was made with the participation of Irish Film Board and produced by Teddy Leifer through his UK-based production company RISE Films.
