Where can I watch Hoop Dreams in United States?

Every school day, African-American teenagers William Gates and Arthur Agee travel 90 minutes each way from inner-city Chicago to St. Joseph High School in Westchester, Illinois, a predominately white suburban school well-known for the excellence of its basketball program. Gates and Agee dream of NBA stardom, and with the support of their close-knit families, they battle the social and physical obstacles that stand in their way. This acclaimed documentary was shot over the course of five years.
