Antonio Margheriti (19 September 1930 – 4 November 2002), also known under the pseudonym Anthony M. Dawson, was an Italian filmmaker.  Margheriti worked in many different genres in the Italian film industry, and was known for his sometimes derivative but often stylish and entertaining science fiction, sword and sandal, horror/giallo, Eurospy, spaghetti western, Vietnam War and action movies that were released to a wide international audience.
