Is it a bird? Is it a plane? No! It's the Mole-Men!

In Superman and the Mole-Men (1951), we join George Reeves' Superman as he confronts a small town that is not playing nice with their underground neighbors. Is it really a big deal that everything the little people touch glows in the dark? Or that they carry a mean looking vacuum cleaner?

In the first Superman theatrical film (not including the serials), we are first exposed to the Superman we would later come to love in the Adventures of Superman (television series, 1952-58).
