To be fair to it, there is less about the metaphorical possibilities of giant spiders in Tarantula (1955) than may be commonly imagined.
It's not exactly a nuclear threat movie, and nor in earnest is it a movie about any communist threat.
If anything Tarantula is a fable about our reliance on science to both get us into messes but also to fix those messes up.
Unlike virtually every other monster and giant monster film of the time, the monsters of Tarantula are born of a benign scientists goofy positive plan to create food for all mankind by simply enlarging domestic animals.
