Warner Bros. is set to premiere a new Thundercats series on the Cartoon Network later this year. But before that came to fruition, a Thundercats CGI adaptation, based on the popular animated series that debuted in 1985, was set to hit theaters in 2012. And it has since been shelved. Today, CGI test footage from this planned big screen outing has leaked online.

The following footage hasn't been classified as official just yet, but the action on display falls in line with concept art that was leaked more than two years ago, when Jerry O'Flaherty was set to direct the project. You can check out the test footage below and decide for yourself.
