Offwidth crack climbing is a strange sub-culture, rumoured to be the domain of knuckle-dragging, bar-brawling dirtbags, and the climbing itself is tough, painful, and bloody. Wide Boyz follows two Englishmen, Pete Whittaker and Tom Randall, who train obsessively in a Sheffield cellar before setting out to climb the world's hardest offwidths in America.

Why This Film Matters: There is something gloriously stubborn about devoting years to the ugliest, most punishing corner of a sport. Wide Boyz is a very funny, very British story of two amateurs who out-worked everyone to master a discipline nobody else wanted, proof that obsession, applied hard enough, can rewrite what is possible.
