Some random thoughts after seeing this trailer for a number of times now.
Zhang Ziyi actually looked like Megumi Odaka from “Godzilla vs. Space Godzilla”.
That meteor that we see is probably Ghidrah coming down to Earth thousands of years ago.
In regards to Godzilla running towards Ghidrah, that could be someone’s thoughts we are seeing, perhaps Millie Bobby Brown’s. A dream scenario?
Many of have noticed that oil derelict, when that monster insect is emerging from the ground. Some have speculated that this could be taking place in the Middle East, since Monarch has a site there. I still think it is Mexico, and the creature is actually serving as food for Rodan (just like in the original).
