We can't think of too many garbagemen in Azeroth -- Topper Mcnabb, maybe? But the fact that Campbell knows about the movie and is ready to take a role is good enough for us. And he isn't the only person speculating on the part he might play: Chris Metzen brought up Campbell at Comic-Con and suggested he might play a CG-based character, like a goblin. That doesn't sound so awesome to us, though -- you've gotta let that world-famous mug shine through. It does seem a little unlikely that Campbell would play a really huge part, but a lot of people have brought up Varian Wrynn, and we can't really think of any part more fitting (plus, maybe that means the movie will focus on Horde instead of Alliance). Hail to the King, baby!
Keep an eye over on our sister site Massively for more Comic-Con coverage all this weekend, and if we hear any more about the movie, we'll be sure to let you know.
