This was reportedly the highest grossing American movie serial of all time.

Lex Luthor was in neither the animated shorts nor the later TV series starring George Reeves; Lyle Talbot was the first actor to ever play the character.

In chapter one the shot of Luthor destroying the bridge is actual footage of the original Tacoma Narrows Bridge that opened in 1940 (also known as "Galloping Gertie"). The footage used is that of the bridge in its final moments prior to its collapse on November 7, 1940, shot on 16mm Kodachrome motion picture film by Barney Elliott and Harbine Monroe of a Tacoma-area camera shop.

The face of Lyle Talbot, who portrayed Lex Luthor in this serial, was used in the comic books as the actual face of Luthor until the 1960s, when a much thinner version of Luthor was premiered.
