O'Halloran once stated in an interview that it was his idea to make Non a childlike character, having difficulty adjusting to his newfound powers and making sounds in the absence of voice. O'Halloran criticized Alexander and Ilya Salkind, the producers of the "Superman" films, for their mishandling of the franchise, believing that their firing of director Donner was a huge blow to the series and the cause of its downturn in quality, a sentiment that was shared by Gene Hackman, who refused to reprise his Lex Luthor role in the third film, and by Margot Kidder who played Lois Lane.
