The Magnetic Monster

Directed by Curt Siodmak

With Richard Carlson, King Donovan, Leo Britt, Jean Byron and Harry Ellerbe

The Office of Scientific Investigations tracks down the source of increased magnetism and radioactivity in Los Angeles, and discovers that a man-made isotope is consuming available energy from nearby mass every few hours, doubling its size in the process. Although microscopic, it will soon become big enough to destroy Earth; and how to stop it is yet to be determined. (The film's Deltatron special effects footage is taken from the 1934 German sci-fi film GOLD.)
