Interesting article. Unfortunately it's about characters that Jack Kirby was working on that never got to see the light of day. Thundarr The Barbarian greeted the light of day every Saturday morning on ABC from 1980 to 1982, then continued to do so in reruns on NBC from 1982 to 1984, and continues to do so to this day on The Cartoon Network and Boomerang, as this very thread is a testament to. Though perhaps Ruby-Spears Productions making cartoons, comic books, and video games out of these never-before-seen Jack Kirby projects might spark an interest in a revival of Thundarr The Barbarian, much like Hanna-Barbra & Warner Brothers launching What's New Scooby Doo? after the success of their animated feature film Scooby Doo On Zombie Island.
I did read on another website that a script for a live action Thundarr The Barbarian movie is being shopped around Hollywood for a producer and/or director. They didn't post any links or cite any sources, like Variety Magazine, Access Hollywood, etc, so that could just be a rumor. I'll post more on the subject if any more information is forthcoming.
