Kryptonite’s Origins Lie Not in Comic Books, But โคin a Rejectedโค superman Script and Radio โShow Demands
New โฃYork, NY – The iconic weakness of Superman, Kryptonite, didn’t โคoriginate in the pages of DC โComics, but rather from a discarded story idea and the logistical needs of a 1940s radio program. A script pennedโ by Supermanโ co-creator Jerry Siegel in 1940, titled “The K-Metal from krypton,” laid the groundwork for the substance that would becomeโ Kryptonite, though it โwas initially rejected by โคDC editors.
The rejected script introduced a “K-Metal” -โข a โฃfragment ofโข Krypton that, like Kryptonite, sappedโค Superman’s powers upon exposure. Crucially, the K-Metal also granted superpowers to any human who touched it. The story was shelved primarily because it featured Superman revealing his secret identity to Lois Lane, aโข change DC was unwilling to make โto the character’s established status โฃquo.
Despite being unpublished,”The K-Metal from Krypton” โคis believed to have heavily influenced the eventual โcreation ofโข Kryptonite. โคThe effects of K-Metal on Superman were nearly identical toโ those โof Kryptonite, andโค both โขsubstances would eventuallyโ reveal aspects of Superman’s Kryptonian heritage.
Interestingly,the introduction of Kryptonite in the Adventures of Superman radio serial in 1943 mayโฃ have been inspired byโข the rejected script. theโค radio show’s creators were reportedly seekingโข a way to temporarily remove โSuperman (actor Bud Collyer) from the program to accommodate โคhisโ other commitments,โ and Kryptonite provided a narrative solution.โฃ
The origin of Kryptonite remains somewhat mysterious, โฃbut theโฃ evidence suggests a confluence of factors – a rejected comic book script and the practicalโ demands of early superhero audio โฃdramas – led to the creation of one of the โmoast recognizable elements of the Superman mythos.
