Did You Know?


In previous movies, Godzilla was an unstoppable villain that only cared about destroying the world. In the prequel to when this suit was used, Ghidrah, the Three Headed Monster, Godzilla became friendly towards people. This suit became the start of Godzilla's infamous "hero of the world" phase. Although Godzilla was still considered a danger in the movies, he still knew that he was to protect the people of Earth. See more »


In one of the shots of the tanks firing at Godzilla and Rodan, a "glass" window in the background keeps wobbling as if made of a sheet of thin plastic. See more »

Banzai, Nick Adams!
7 August 2006 | by (Japan) – See all my reviews

The other day I found this movie at a nearby video shop by chance. Contrary to my anticipation, I found this movie quite fun. The movie I saw was in Japanese and Nick Adams' voice was dubbed, but his acting was pretty good, though he pulled up his pants a lot.

This brought me good memories of Mr. Adams. As a kid about ten years old at that time, my father (who was the USA representative for Toho and manager of the Toho La Brea Theatre) and I went to the LA airport to see him off. He was going to Japan to take this movie. He was very friendly and relaxed, he was with his wife and his little boy, he looked very happy and energetic. I remember asking him, Mr. Adams, how are fight scenes taken in movies? He replied with a nice big smile and with a fighting gesture, we really fight and punch! Gasshou! meaning I join my palms together for Mr. Adams and for my late father.
