Which movie or TV show starts with the most perfect image?S

Sometimes a great director can speak volumes with a single image, right at the beginning of a story. The best movies and TV shows often start off with a single stark frame, that stays with you as you watch the story unfold. But what's the best opening shot in science fiction or fantasy history?

Please include a picture or clip of this beautiful shot. And mention the name of the thing it comes from. Thanks!
