, the Atom Man, invents a number of deadly devices to plague the city, including a disintegrating machine which can reduce people to their basic atoms and reassemble them in another place. But Superman manages to thwart each scheme. Since Kryptonite can rob Superman of his powers, Luthor decides to create a synthetic Kryptonite and putters about obtaining the necessary ingredients: plutonium, radium and the undefined 'etc.' Luthor places the Kryptonite at the launching of a ship, with Superman in attendance. He is exposed to the Kryptonite and passes out. Superman is taken off in an ambulance driven by Luthor's henchmen, and he is now under the control of Luthor. Superman is placed in a device, a lever is pulled, and the Man of Steel vanishes into "The Empty Doom".
Lyle Talbot, who had previously starred as Commissioner Jim Gordon in the 1949 Columbia Serial Batman and Robin, here portrays Lex Luthor. In his "Atom Man" disguise, Talbot as Luthor, utilizes a vaguely German accent and wears an ominous mask fashioned from a "Metallogen Man" robot costume left over from 1945's The Monster and the Ape. Despite their onscreen personas, Talbot, who wore a rubber scalp to create the impression of baldness, and Alyn spent much of their time, when not shooting, exchanging recipes; both actors shared an interest in cookery.
Special effects
The final set piece shows Metropolis under attack by "poorly animated" flying saucers and a torpedo. The flying effects were somewhat improved in this film than in the original, by the simple expedient of turning the camera on its side. Kirk Alyn stood with arms raised in front of a cyclorama, while a wind machine and smoke pot were placed above him. This gave an inexpensive illusion of flight. Longer shots continued to use cartoon animation of the Man of Steel.
Critical appraisal
In their book The Great Movie Serials, Jim Harman and Donald F. Glut describe the serial as "far more gimmicky and gadget prone" than the first Superman serial. In addition to this, they also found it to be "flawed by the same Katzman cheapness."
