Hoop Dreams (PBS, 8-11 p.m.): Originally conceived as a public-television project, this documentary about two inner-city teens was instead released theatrically in 1994. Now, after garnering critical praise and popular appeal, the film makes its debut on the small screen.
The film follows the daily lives of Arthur Agee Jr. and William Gates, two young basketball players who dream of playing in the NBA. As they pursue their goals on the court, other issues come into play: academic requirements, family commitments, and financial circumstances.
Following at 11 p.m. is ''A Hoop Dreams Reunion,'' a half-hour update on Agee, Gates, and their families, plus interviews with the filmmakers.
