Supermans Secret Identity July 15, 2009 Superman co-creator Joe Shuster’s secret life is set for the big screen! Superman co-creator Joe Shuster’s life is set for the big screen in a new biopic. The Gotham Group movie will be based on Craig Yoe’s recent book Secret Identity: The Fetish Art Of Superman’s Co-Creator Joe Shuster. The book claims that Shuster was the unnamed artist behind the mob-backed Nights Of Horror S&M and torture series.The comics, sold under the counter at Times Square bookshops, ignited a scandal due to their controversial illustrations and alleged inspiration for a group of criminals called the Brooklyn Thrill Killers. Shuster’s Superman collaborator Jerry Siegel hit the headlines last week when his heirs lost a ruling in their case to claim a share of Superman profits from Warner Bros and DC Comics.
