Superman is a 1948 15-part Columbia Pictures film serial based on the comic book character Superman. It stars an uncredited Kirk Alyn and Noel Neill as Lois Lane. Like Batman (1943), it is notable as the first live-action appearance of Superman on film, and for the longevity of its distribution. The serial was directed by Thomas Carr, who later directed many early episodes of the Adventures of Superman television series, and Spencer Gordon Bennet, produced by Sam Katzman, and shot in and around Los Angeles, California. It was originally screened at movie matinées, and after the first three scene-setting chapters, every episode ends in a cliffhanger. The Superman-in-flight scenes are animations, in part due to the small production budget.

Columbia Pictures Industries, Inc., commonly known as Columbia Pictures or simply Columbia, is an American film production and distribution company that is a member of the Sony Pictures Motion Picture Group, a division of Sony Pictures Entertainment, which is one of the Big Five studios and a subsidiary of the multinational conglomerate Sony.
