Scaling is used a lot in monster movies, and movies where a large effect needs to happen on large objects, and where audiences are forced to realize the magnitudes of objects. The two instances that I can think of is the movie Independence Day which features physical scaling for special effects, and Godzilla: King of Monsters, where Godzilla and King Ghidorah where they show the two monsters side by side. In Independence Day, when New York City was being destroyed, a great wall of fire comes rushing at the audience and pushing Boomer (the dog) into a tunnel with his owner. This effect was made by making a small scale model of New York City, turning it sideways, and then blasting fire onto the model. This made the effect look much more devastating and realistic.
In Godzilla: King of Monsters, there is one scene in particular that really shows how massive these creatures are, even compared to each other.
We see King Ghidorah to the left and Godzilla to the right, and in the middle, there is a very very small speck which is an entire hovercraft, filled with people. In this photo King Ghidorah towers over Godzilla. The size difference between the two is massive. I think that is really what makes this scene so jarring. The audience is thinking, the “good guy” is so much smaller than the bad, and then look at the puny humans in between that do not stand a chance.
I wanted to mention both types of scaling, because they both can play a big role in film making, but are used very differently.
