Producers Richard D. Zanuck and his wife, Lili Fini Zanuck, co-owned the rights to the sequel with 20th Century-Fox. Initially opposed to the concept of a second film, they only went ahead with it out of a need to preserve the integrity of the original. As it transpired, Lili, who was very much opposed to doing a sequel, had only nominal interest as she was busy prepping her own directorial debut, Rush (1991).
