Michael Rooker, who was fantastic on his now-completed run on AMC’s The Walking Dead, has been cast as one of the four founding superheroes of Guardians Of The Galaxy, the Marvel Studios pic that James Gunn is helming. He will play Yondu, who in Marvel lore was a game hunter of a primitive tribe native to Centauri IV, the first planet system to be colonized outside of the Sun’s solar system. He eventually bands together with fellow fugitives to form the superhero team. Chris Pratt already has been cast, and Disney plans an August 1, 2014 release date. Rooker, whose film credits include Mississippi Burning, Days of Thunder, JFK, Tombstone and Jumper, is repped by Kritzer Levine Wilkins Griffin Nilon Entertainment.
