I watched James and the Giant Peach again recently. I never actually got to see it when it came out. I vaguely remember that my mother, for some reason, did not like it. I think maybe she just found Tim Burton's stop-motion shit weird in general because I remember having wanted to see The Nightmare Before Christmas too and we never did. So instead, I had a phase a few years after high school where I "caught up" on some of the Disney movies I missed out on and this was one of my favorites.
What I have been thinking about mostly since having rewatched it is how they translated the insects into their more "human" forms and then animated them to reflect both sides of that. Some of them, Grasshopper and Centipede, were made more humanoid with insect characteristics like their multiple arms and antennas. Others strike sort of a middle ground where they have rather unavoidable insect characteristics that need to be accounted for. Ladybug's large round body and Glowworms's bioluminescent tail specifically. Then there's Earthworm and Spider, who could only really just be made as larger versions of their actual species.
