20,000 MILLION MILES TO EARTH (1957) is one of the early black-and-white science fiction films from Ray Harryhausen, the special effects expert who used stop-motion techniques to bring numerous monsters to life throughout his long career. Thanks to Google Video, you can watch this classic example of his work for free. It’s all about an Ymir (a creature from Venus) that hitches a ride to Earth on a space probe.
