It seems the Godzilla (2014) sequel is using a throwback to the old Mothra film to explain how Rodan, Mothra and King Ghidorah all come to trade blows with Godzilla. In that classic film, Mothra was controlled by a set of twins that hailed from a remote tribe that worshipped the giant insect. In the new film, the kaiju will be controlled by more scientific means.
Speaking to Metro, Vera Farmiga revealed, "I play a paleobiologist. She has figured out a way to communicate with the creatures and potentially control them using their bioacoustics on a sonar level. So she is like a DJ for the monsters."
Probably not something Legendary and WB wanted spoiled at this early juncture.
Godzilla: King of the Monsters stomps its way into theaters on May 31, 2019.
About Godzilla: King of the Monsters
The new story follows the heroic efforts of the crypto-zoological agency Monarch as its members face off against a battery of god-sized monsters, including the mighty Godzilla, who collides with Mothra, Rodan, and his ultimate nemesis, the three-headed King Ghidorah. When these ancient super-species—thought to be mere myths—rise again, they all vie for supremacy, leaving humanity’s very existence hanging in the balance.
