 An original idea for this movie had Godzilla fighting the original  1954 Godzilla in ghost form. The project, "Godzilla VS Ghost  Godzilla", was scrapped because the producers thought Godzilla  didnt need to fight a clone version of himself for three movies in  a row, following Godzilla VS Mechagodzilla (1993) and Godzilla VS  Spacegodzilla (1994). They opted for this idea instead.
