Superman and the Mole-Men

Superman and the Mole Men is an independently made 1951 American black-and-white superhero film, produced by Barney A. Sarecky, directed by Lee Sholem, that stars George Reeves as Superman and Phyllis Coates as Lois Lane. The film, the first theatrical feature film based on any DC Comics character, was released by Lippert Pictures Inc. The storyline concerns reporters Clark Kent and Lois Lane arriving in the small town of Silsby to witness the drilling of the world's deepest oil well. The drill, however, has penetrated the underground home of a race of small, bald humanoids who, out of curiosity, climb to the surface at night. They glow in the dark, which scares the local townfolk, who form a mob intent on killing the strange visitors. Only Superman can intervene to prevent a tragedy.
