<P> 20 Million Miles to Earth began production in Rome , Italy in September 1956 , using only William Hopper of the main cast , and moved to the U.S. from October 30 to November 9 of that year . Rome was chosen as the location for filming because Harryhausen wanted to vacation there . The working title of the film was The Giant Ymir , and it has also been released as The Beast from Space . All references to the name Ymir were removed from the released version of the film , as Harryhausen was concerned that audiences might confuse it with the Arabic title `` Emir '' . </P>
