 The concept for the film came from a story contest that Toho held in  1986, which was to decide on the narrative for the next installment  in the Godzilla series. Jim Bannon was the contestant who was noted  for his Godzilla 2 script, which had Godzilla facing off against a  giant computer, but was beat out by Shinichiro Kobayashi with his  early draft for Godzilla vs. Biollante. However, Toho didnt scrap  Bannons second place entry, but instead had Masato Harada heavily  rework the idea, removing Godzilla and other elements from the film,  until they were left with the final product: the infamous Gunhed.
