There's a Japanese live-action horror film Marebito, which focuses on beings called Detrimental Robots or Dero for short. The film depicts these beings as pale-skinned underground dwellers hostile to humans.

I guess what I'm asking is did hearing of these beings isnpire the Derro in the MM?

According to wiki and several other sites dero come from Richard sharpe Shaver's stories that he claims are all true

Yeah, but did Shapre's stories influence the creation of the D&D monster Derro?

Ehh really hard to tell best thing to do is find out first time the Derro were printed and them cross check if sharpe's came first then it's a possibility but who knows
