According to Seen, Henry Chalfant originally intended to make a documentary about breakdancing but felt that he did not have enough interesting footage. So he instead focused on graffiti art and combined the footage which led to graffiti art becoming associated with hip-hop culture.
Cap originally wanted to hide his face by wearing a ski mask. The producers reluctantly agreed. But Cap showed up to filming without the mask and decided to let his face be seen.
Henry Chalfant was originally against having Cap appear in the film because he had become friendly with the graffiti artists whose work Cap had ruined. But Tony Silver insisted that Cap appear because his name was repeatedly mentioned by the artists. Some of the artists felt betrayed by Chalfant because they felt that he gave Cap the attention that he sought.
