The Cat o' Nine Tails (Italian: Il gatto a nove code) is a 1971 giallo film written and directed by Dario Argento, adapted from a story by Dardano Sacchetti, Luigi Cozzi, and an uncredited Bryan Edgar Wallace. It stars Karl Malden, James Franciscus, and Catherine Spaak. The film was a commercial success in Italy but not in the rest of Europe. However, it was acclaimed in the United States. Argento admitted in the book Broken Mirrors, Broken Minds: The Dark Dreams of Dario Argento that he was less than pleased with the film, and has repeatedly cited it as his least favorite of all of his films.
