Michelle Williams has signed on for Sam Raimi's Oz, the Great and Powerful in the role of Glinda, the Good Witch, Variety reports.
The Disney release, a prequel to the 1939 The Wizard of Oz, will star James Franco as a younger version of the Wizard from the original film, who winds up in Oz following a balloon accident.
Mila Kunis is also attached in the role of Theodora, another good witch while Rachel Weisz is in negotiations for Evanora, a wicked witch.
Glinda was famously portrayed by Billie Burke in the 1939 film version where the character was referred to as "the Good Witch of the North" and not "the Good Witch of the South", which is how she was originally represented in the L. Frank Baum novel. Though still-unannounced, Glinda's title in the Raimi version might be the first clue to what source material the production has elected from which to draw.
Michelle Williams recently appeared in Blue Valentine and Shutter Island and is soon set to play Marilyn Monroe in the upcoming My Week With Marilyn.
