<Li> Bart Bradley as Pepe </Li> <Li> Ray Harryhausen cameo (uncredited) </Li> <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> <P> Ray Harryhausen wanted the film to be shot in color, but the filmmakers were not given a budget large enough to accommodate color filming . In 2007, five years after the death of the film's director, Harryhausen worked with restoration and colorization company Legend Films to create a colorized version of the film . That version, along with the original theatrical black - and - white version, was released July 31, 2007 on DVD as part of a 50th Anniversary Edition of the film . </P>
