Filmed over 12 years, Knuckle is the story of a family feud like no other. For several decades, clans from the ethnic minority of Irish Travellers have settled their differences, fairly but brutally, in organised roadside boxing matches. While understandably dubbed the Fight Club of documentaries, this is a family affair – our tenacious bare-knuckled fighters, born with generations-old chips on their shoulders, reluctantly fight to preserve the honour of their family name. Director Ian Palmer was afforded an amazing degree of access to pugilists on both sides of this gritty war.
