I just re-watched the JSA episode of Smallville, and what with their recent appearances on DC Legends it got me thinking: what JSA members have appeared on tv or movies? Here's what I've got:
Superman (the Kirk Allyn version is most certainly Earth 2; Batman(same for the two serials; Flash and Jesse Quick (the CW's Flash; Dr Fate, Sandman, Hawkman, Stargirl (Smallville); Obsidian, Stargirl, Hourman, Commander Steel, Dr Midnite (DC Legends); Wonder Woman (first season of the tv show was WWII era); Mr Terrific, Black Canary and Wildcat(Arrow);
Red Tornado (Supergirl). Any others?
