Bakshi went to England to recruit a voice cast from the BBC Drama Repertory Company, including Christopher Guard, William Squire, Michael Scholes, Anthony Daniels, and John Hurt. Daniels remembers that "The whole cast were in the same studio but we all had to leave a two second gap between the lines which made for rather stilted dialogue.""" For the live-action portion of the production, Bakshi and his cast and crew went to Spain, where the rotoscope models acted out their parts in costume in the open or in empty soundstages. Additional photography took place in Death Valley. Bakshi was so terrified of the horses used in the shoot that he directed those scenes from inside the caravan.
