Producer Spike Lee believed the female lead should have believable basketball skills. Gina Prince-Bythewood said in an interview "I saw over 700 people for the part: actors, ballplayers, people who had never acted before in their life. It finally came down to Sanaa [Lathan] and Niesha Butler [a star player at Georgia Tech and 1999 Atlantic Coast Conference rookie of the year]. I put Sanaa with a basketball coach for two months and Niesha with an acting coach."
In an interview with the Los Angeles Times, Sanaa Lathan said her basketball tryout was terrible because she'd never played before. "It was so embarrassing because literally I didn't know how to dribble. I didn't know how to hold the ball. But I'm proud of how it looks [in the movie]. I had no idea I would be able to do it."
In 1981, when the movie begins, Quincy's father plays for the Clippers. However, the family lives, and his father plays, in Los Angeles. The Clippers didn't move from San Diego until 1984.
