Godzilla's movements and mannerisms namely the scene where he's sleeping curled up inside the Roman Colosseum, were based off of director Adam Wingard's cat 'Mischief.'
With a net budget of $135 million, this is the cheapest MonsterVerse film to date.
The image used for the blueprint of the B.E.A.S.T. Glove is the arm of the Pacific Rim (2013) jaeger, Gipsy Danger.
For Godzilla and Kong's new looks, Adam Wingard revealed: "Very specifically in the last film, I wanted Godzilla to have a continuity, to look the way that he had in 'King of the Monsters' and the 2014 'Godzilla.' But then I didn't get a chance at doing my version of Godzilla. So now I wanted to do different things with the spines and try different colors. I didn't want it to just be random; it's part of the story. And similarly, with Kong, I wanted to give him some sort of new look as well. We grew his beard out, and gave him a little bit more grey hair and stuff."
Godzilla has 8 minutes of screen-time, which as actually the least amount in the Monsterverse movie at the time of release. For comparison this is 3 minutes less than Godzilla vs. Kong (2021) (which was 11 minutes), and 2 minutes less than Godzilla: King of the Monsters (2019) (which was 10 minutes) and Godzilla (2014) (which was 10 minutes).
