Austrian-born Nathan Juran was a professional architect before entering the film industry as an art director in 1937. He won an Academy Award for art direction on How Green Was My Valley (1941). World War II interrupted his film career, and he spent his war years with the OSS. Returning to Hollywood, he turned to directing films in the 1950s. He handled mostly low-budget westerns and sci-fi opuses, his most famous (or infamous) being Attack of the 50 Foot Woman (1958) (which he filmed under the name "Nathan Hertz"). On the other hand, he was also responsible for the superb fantasy adventure The 7th Voyage of Sinbad (1958). In the early 1960s, he journeyed to Europe, where he spent several years piloting adventure epics and spaghetti westerns.
