Editing Son of Godzilla (section)

===Special effects===
The Godzilla suit built for this film was the biggest in terms of size and girth.{{sfn|Kaneko|Nakajima|1983|p=101}} This was done in order to give Godzilla a "paternal" appearance and to give a parent-like stature in contrast next to Minilla.{{sfn|Kabushiki|1993|p=64}} Because of the size of the suit, seasoned Godzilla suit actor [[Haruo Nakajima]] was only hired to play Godzilla in two scenes because the suit was much too big for him to wear.<ref>''Haruo Nakajima Monster Photo Book''(中島春雄怪獣写真集). Yuizumi Publishing. 2014. Pg.264</ref> The smaller suit he had worn for the films ''Ebirah, Horror of the Deep'' and ''[[Invasion of Astro-Monster]]'' was used for these sequences.{{sfn|Ryfle|1998|p=142}} The much larger Seji Onaka instead played Godzilla in the film, although he was replaced midway through filming by Hiroshi Sekita after he broke his fingers.{{sfn|Ryfle|1998|p=143}}

Minilla was designed to incorporate features of not only a baby Godzilla but a human baby was well.{{sfn|Kabushiki|1993|p=64}} Minilla's face was patterned after the character Chibita from the popular manga ''[[Osomatsu-kun]]'' published by Shogakukan in Weekly Shonen Saturday at the time. "Marchan the Dwarf" was hired to play the character due to his ability to play-act and to give the character a childlike ambiance. He was also hired because of his ability to perform athletic rolls and flips inside the thick rubber suit.{{sfn|Kabushiki|1993|p=64}}

Outside of the two monster suits, various marionettes and puppets were used to portray the Island's gigantic inhabitants. The various giant preying mantises known as [[Kamacuras]] and the huge spider Kumonga.{{sfn|Kaneko|Nakajima|1983|p=76}}{{sfn|Kaneko|Nakajima|1983|p=77}} Arikawa would usually have 20 puppeteers at a time working on the various marionettes.{{sfn|Ryfle|1998|p=143}} The massive Kumonga puppet needed 2 to 3 people at a time to operate each leg.{{sfn|Ryfle|1998|p=143}}

Styrofoam and paraffin were used for the snow falling on Solgell Island.
