many of the animators who worked on the film were professionals that bakshi had previously worked with at terrytoons, including jim tyer, john gentilella, nick tafuri, martin taras, larry riley, and cliff augustine. according to bakshi, it took quite a long time to assemble the right staff. those who entered with a smirk, "wanting to be very dirty and draw filthy pictures", did not stay very long, and neither did those with a low tolerance for vulgarity. one cartoonist refused to draw a black crow shooting a pig policeman. two female animators quit; one because she could not bring herself to tell her children what she did for a living, the other because she refused to draw exposed breasts.
