Recent casting for the DC Universeseries Stargirl show the Justice Society roots of the character. Variety is reporting that Joel McHale (Community) will be cast as what is described as the "Golden Age Starman" aka. Sylvester Pemberton aka. The Star-Spangled Kid in the comics. In said comics, he was given the Cosmic Rod/Staff by Starman Ted Knight, and created the Cosmic Converter Belt, which was later used by Stargirl.
Another Golden Age character being added to Stargirl is Rex Tyler aka. Hourman. As reported by TVLine, Lou Ferrigno Jr. (S.W.A.T.) will be playing that role. Hourman discovered the miracle drug Miraclo, which gives the user super human strength, super speed, and durability for one hour. And yes, Ferrigno Jr. is the son of the man who played the Hulk from the 1970s TV series.
