Director Sam Raimi stopped by Comic-Con today to unveil the first teaser for Oz: The Great and Powerful. The film, which takes place in the time before the iconic The Wizard of Oz, follows Oz (James Franco) on his journey from being a dishonest magician in Kansas to coming into his own in the Emerald City. He gets some help from Glinda (Michelle Williams) and also encounters witchy sisters Theodora (Mila Kunis) and Evanora (Rachel Weisz).The teaser doesn't give away much, but it certainly has that Wizard of Oz feel, starting off in black and white before going into full technicolor. I got to see the preview during the panel at Comic-Con and was blown away by how amazing the 3D looked, especially as Oz journeys to Oz via balloon. The film hits theaters next March, but check out the trailer and tell us what you think!
