Ladd, who had produced the successful international, English-language adaptation of Astro Boy, and Al Singer formed a corporation called Delphi Associates, Inc. to produce and distribute an English-language version of Tetsujin 28-gō. They took only 52 episodes of the black-and-white Japanese series for the American market and renamed the series Gigantor. Peter Fernandez wrote much of the English script and participated in the dubbing. Delphi then sub-licensed worldwide distribution rights to Trans-Lux Television. The series became an immediate hit with juvenile audiences, though adult reactions were sometimes hostile.
