 The classic Toho monsters Angilas and Varan were originally  considered by writer/director Shusuke Kaneko (qv) besides Baragon,  but Toho asked Kaneko to replace the two with King Ghidorah and  Mothra because Angilas and Varan were not considered marketable  (Ghidorah, Mothra and Baragon are among the most popular of the Toho  monsters next to Godzilla). However, before this change, concept  maquettes of Angilas and Varan as they wouldve appeared in this  film, were made (by the films monster designer,  Fuyuki Shinada (qv).
