Let me outline:
Released in 2002 and directed by Ellory Elkayem, Eight Legged Freaks is a loving homage to 1950s B-movies, particularly giant monster films like Tarantula! and Them! The plot is delightfully simple: toxic waste spills near a small Arizona mining town, causing spiders to mutate into colossal, man-eating arachnids. David Arquette stars as Chris McCormick, a former resident who returns to town just in time to help the quirky locals – including a tough-as-nails sheriff (Kari Wührer) and her conspiracy-theorist son (Scott Terra) – fight back.
