Not only does this need to be a movie, but I think we need an entire dream cast. Come on, internet. Be awesome.
Casting suggestions for (and if you choose CGI for anyone, please mention voice cast please?):
The Wicked Witch (edit: I had a question of if the witch is alive. But, hey...it's a sequel. You know how that goes. Zombie Witch perhaps?)
if you have more...heck, go for it ::grin::
(Oh, once upon a time I used to know how to write a "breakdown" but my days in casting have long passed.)
