According to special-effects auteur Ray Harryhausen, "We would have been shot in color if we could have afforded it. . . . The color sure improves it." That's what Harryhausen says on the commentary track for his 1957 classic, "20 Million Miles to Earth," which arrives Tuesday in a two-disc 50th anniversary special edition set ($24.96). The first disc contains full-frame and anamorphic versions of the film in black-and-white, as well as the newly colorized edition, which Harryhausen personally supervised. [More]
