	Almost all of the film's dialogue, except for that of a few of the main characters, was recorded entirely on the streets of New York City. For the film's opening sequence, Bakshi paid two construction workers US$50 each, and drank Scotch whisky with them, recording the conversation. In the Washington Square Park sequence, only Skip Hinnant was a professional actor; Fritz's friends were voiced by young males Bakshi found in the park. One of the sequences that was not based upon Crumb's comics involved a comic chase through a synagogue full of praying rabbis. For the voices of the rabbis, Bakshi used a documentary recording of his father and uncles. This scene continued to have a personal significance on Bakshi after his father and uncle died. Bakshi states, "Thank God I have their voices. I have my dad and family praying. It's so nice to hear now." Bakshi also went to a Harlem bar with a tape recorder and spent hours talking to black patrons, getting drunk with them as he asked them questions.
