Steve James' essential inner-city epic chronicles the lives of two young blacks growing up in a Chicago housing project. At 14, basketball prodigies Arthur Agee and William Gates win scholarships to a suburban high school, St Joseph's. Then their fortunes diverge. William looks set to follow in the footsteps of St Joe's favourite son, all-star Isiah Thomas. Arthur doesn't make the cut. Skinny and immature, he finds himself back in the inner city when his parents fall behind on the fees. Over the next four years, however, the boys' lives are to intersect more than once, and in unexpected ways. A three-hour documentary about basketball is probably not most people's idea of a night out, but this one rewards the effort. James and his collaborators shot more than 250 hours of footage, and the cumulative emotional power is simply devastating. Sport is the only dream Arthur and William are allowed, their only ticket out of the ghetto, but they also have to carry the weight of their parents' aspirations - and if they make it, they will become role models for thousands of kids just like them. Unforgettable.
