Directed by: Jack Arnold
Starring: John Agar, Leo G. Carroll, Mara Corday, Nestor Paiva
Continuity mistake: Just before the giant tarantula attacks the house where heroine Mara Corday is studying, you can see several book on the library table at the big picture window. The largest book on the table keeps shifting positions in several scenes.
Factual error: When they are driving in the convertible, before the tarantula attacks them with the stones, if you look at their hair, it's not moving with the wind. If they were driving a convertible that fast in real life, it would.
Dr. Matt Hastings: Give women the vote and what do you get? Lady scientists.
Trivia: Clint Eastwood filmed his very first big-screen role as a jet fighter pilot (an uncredited speaking part) in 1955's "Tarantula"; later that afternoon on another set, Eastwood filmed his role as a lab assistant (a more extensive speaking role) in 1955's "Revenge of the Creature," making it a big day for a Hollywood newcomer.
