I want Bruce Campbell's cameo, cause you know that he will have one, to be as Autolycus King of Thieves. He was my favorite character in the Xena/herc verse.
As for the movie... it's going to bomb. Bomb in a way that's not humanly possible, but Sam Raimi will find a way to run this idea so far into the ground it's going to come out in china.
There is SOOOO much they could use to make a movie, hell you could get 3-6 movies out of the backstory from the Warcraft verse. The rise of Thrall could be a great first movie.
