Michael Clarke Duncan in talks to voice Kilowog in Green Lantern

A little late in the game to be adding voice actors, isn't it? Green Lantern is due to open in June, but Latino Review reports that Michael Clarke Duncan is in talks to voice the mammoth Kilowog in the film. Again, this seems a little odd. I mean, there's been some talk about there being some post-production issues, which explains why we haven't seen much on the film since the trailer. But hasn't Dennis Haysbert(Far From Heaven) been voicing Kilowog all this time? 

Whatever. I prefer Duncan anyway.  Kilowog is probably the meanest and toughest member of the Green Lantern Corps. He's the guy who trains Ryan Reynolds, and can be seen in the trailer as the giant creature snorting right in his face.
