TRAILER: Will James Franco Become 'Oz: The Great and Powerful' and Save Mila Kunis, Rachel Weisz and Michelle Williams?

Welcome to Oz. To go along with those pictures from Oz: The Great and Powerful earlier this week, Disney has now released a full trailer for the upcoming movie. This is the most in-depth look we've gotten at director Sam Raimi's Wizard of Oz prequel yet, with a few interesting plot points now revealed. Maybe I misinterpreted what the witches were saying, but I'm under the impression that Mila Kunis and Rachel Weisz's witches (who are presumably the wicked witches) refer to Michelle Williams' Glenda as the wicked witch. Interesting spin on things.

Oz: The Great and Powerful stars James Franco as the man who would become the Wizard of Oz. It opens on March 8, 2013. Check out the trailer after the jump.
