Tarantula! is a 1955 American science-fiction, giant monster film from Universal-International, produced by William Alland, directed by Jack Arnold, and starred 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", also directed by Arnold.[1]
