Extended new 'Oz' trailer debuts

Disney has released a second, longer trailer for "Oz the Great and Powerful," starring James Franco as a Kansas man who enters a strange new land and finds himself heralded as a wizard. Franco's witchy co-stars include Mila Kunis as Theodora, Rachel Weisz as Evanora and Michelle Williams as Glinda.

Ah, but who plays the Wicked Witch? The trailer isn't revealing that, and neither is Disney. Rumors say it's Kunis, who reportedly dropped a dark hint about her character at Comic-Con in July.

"Oz the Great and Powerful" is directed by Sam Raimi and scheduled for release March 8.
