 This was Jerry Goldsmith (qv)s first music score for an animated  film. He later said that it was among his personal favorites. He was  instrumental in introducing the film to Steven Spielberg (I) (qv),  who went on to work with Bluth on "An American Tail". According to  Bluth and Goldman in their DVD commentary, Goldsmith so loved the  film that he volunteered an extra three weeks to polish and refine  the score, even though he was not contractually obligated to do so.
