the film's voice cast includes skip hinnant, rosetta lenoire, john mccurry, judy engles, and comic book distributor/convention organizer phil seuling. hinnant, who would become known as a featured performer on "the electric company", was cast because he "had such a naturally phony voice", according to bakshi. bakshi and seuling improvised their dialogue as comically inept pig officers; bakshi enjoyed working as a voice actor and later went on to provide voice roles for some of his other films. bakshi re-created the voice he did in this film for the part of a storm trooper in his 1977 animated science fiction film "wizards".
