"Mars and Beyond" is an episode of Disneyland which aired on December 4, 1957. It was directed by Ward Kimball and narrated by Paul Frees. This episode discusses the possibility of life on other planets, especially Mars. It begins with an introduction of Walt Disney and his robot friend Garco, who provide a brief overview. It continues with an animated presentation about mankind seeking to understand the world in which he lives, first noticing patterns in the stars, and developing certain beliefs regarding the celestial bodies. Theories from scientists and philosophers are discussed, including Ptolemy's inaccurate, but formerly-accepted theories, as well as those of Copernicus. Life on other planets is considered, soon focusing on Mars. Ideas from science-fiction authors H.G. Wells and Edgar Rice Burroughs are brought to life with more colorful animation. Pulp science fiction comics of the time are parodied in the same straightforward tone as everything else.

After this, the program adopts a serious tone as it profiles each of the planets in the solar system, from the perspective of what would happen to a man on them. The program claims that whereas most of the planets are either too cold or too hot for life as we know it, life on Mars could almost be normal, something that is of increasing importance for the future. Dr. E.C. Slipher then discusses the Red Planet and the possibility that life is already there. More animation speculates what the conditions on Mars might be like. This section is filled with striking, inventive and atypical Disney animation.
