Continuity mistake: Sakurai is having a steak dinner at home; in the close-up of the two steaks and fries, one of the men is holding a beer glass with their right hand, but it's not the case in the next shot. (00:07:40)
Continuity mistake: In this movie, Godzilla is shown to have a weakness to electricity. This directly contradicts the earlier films where electricity has no effect on him.
Revealing mistake: Godzilla just reached the coast and is fighting a horde of toy tanks. When she sets foot on the base and swings her tail at the control tower, you can see that the tower is pre-broken in the middle, already all cracked and ready to fall apart at the center when Godzilla barely touched the tip. (00:15:10)
Furue: What's happening?
Osamu Sakurai: Giant octopus. Hurry.
Trivia: For a long time, it was rumored among fans that there were two different endings: one where Godzilla wins for the Japanese release and one where King Kong wins for the American release. This rumor was a myth. In reality, only one ending exists: the one where King Kong and Godzilla fall into the sea, and then a moment later, only Kong is shown coming out.
