Tarantula

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 film is about a scientist developing a miracle nutrient to feed a rapidly growing human population. In its unperfected state, the nutrient causes extraordinarily rapid growth, creating a deadly problem when a tarantula test subject escapes and continues to grow larger and larger. 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. The film was distributed by Universal Pictures as a Universal-International release, and reissued in 1962 through Sherman S. Krellberg's Ultra Pictures.
