The scenes shot for the US version were shot at Visual Drama Inc., 129 North Vermont Avenue in Los Angeles, California. Today, the former studio is now the Frank del Olmo Elementary School (formerly Belmont Elementary). On March 25, 2006, a plaque was dedicated at the school in commemoration of the 50th Anniversary of the film's release in the US, a collaboration between the Godzilla Society of North America and Platrix Chapter No. 2, E Clampus Vitus.
The working title for the American version before the "King of Monsters" was added was "Godzilla, the Sea Monster".
Was the first anamorphic widescreen film ever released by Tôhô Kabushiki Kaisha.
