Animator and director Genndy Tartakovsky recently had one of of long gestating superhero dreams realized when his Marvel comic "CAGE!" finally was announced for publication. But that book is far from the artist's only brush with caped adventures.

Recently, plans for Tartakovsky's abandoned "Superman" short film have resurfaced online. The source is a post on background artist Scott Wills' personal blog highlighting some concept art for a short planned as part of Warner Bros. Animation's now shuttered "DC Nation" line.

"Genndy Tartakovsky, [production designer] Justin Thompson and I were very excited to do our take on an animated Superman," Wills wrote. "But unfortunately it was pulled from us just as we were starting." The concept art shows a cinematic take on the Man of Steel well in line with the "Samurai Jack" creator's other work.

Launched in 2011, the DC Nation series allowed a variety of animation talents to put more idiosyncratic takes on the pantheon of DC Comics heroes. The program launched the series "Teen Titans Go!" alongside several shorter-lived yet fan favorite selections before ending in 2013.

Stay tuned to CBR News for a lengthy interview with Tartakovsky on another lost DC project as well as his return to "Samurai Jack" and other incoming animation projects.
