"Tarantula"

A spider escapes from an isolated Arizona desert laboratory experimenting in gigantism and grows to tremendous size as it wreaks havoc on the local inhabitants.

Tarantula is a 1955 American science-fiction monster film produced by William Alland and directed by Jack Arnold. It stars John Agar, Mara Corday, and Leo G. Carroll.

The screenplay by Robert M. Fresco and Martin Berkeley was based on a story by Arnold, which was in turn inspired by Fresco's teleplay for the 1955 Science Fiction Theatre episode "No Food for Thought"
