	Some scenes used documentary recordings which were made by Bakshi and edited to fit the scene; these were used because Bakshi wanted the film to "feel real". According to Bakshi, "I made tons and tons of tapes.  ... When I went to have the film mixed, the sound engineers gave me all kinds of crap about the tracks not being professionally recorded; they didn't even want to mix the noise of bottles breaking in the background, street noise, tape hiss, all kinds of shit. They said it was unprofessional, but I didn't care." Although the sound designers insisted that Bakshi needed to re-record the dialogue in the studio, Bakshi persisted on their inclusion.
