Michelle Williams is set to stir things up as Glinda (The Good Witch of the North) in director Sam Raimi’s Wizard of Oz prequel Oz, the Great and Powerful. The 30-year-old stunner joins a cast that includes Mila Kunis as Theodora (Wicked Witch of the West), Rachel Weisz as Evanora (Wicked Witch of the East), and James Franco as the soon-to-be wizard.

Oz, the Great and Powerful tells the tale of how a lost snake oil salesman and illusionist (Franco) defeats evil witches Theodora (Kunis) and Evanora (Weisz) with the help of  their sister Gilda (Williams) to rule the land of Oz. The film goes into production in July and is slated for 2012 fall release.

Williams, who made her genre debut at age 15 as Young Sil in the 1995 sci-fi classic Species, received an Oscar nomination this year for her performance in the relationship drama Blue Valentine. Her horror creds include 1998’s Halloween H20: 20 Years Later and the slightly better-reviewed 2010 Martin Scorsese thriller Shutter Island.
