Disney may have found the final piece of its triumvirate of witches for its Oz movie: Michelle Williams.

Williams has been offered the role of Glinda, the good witch, in Oz: The Great and Powerful, Disney’s prequel-ish take on The Wizard of Oz tale that stars James Franco and Mila Kunis and is being directed by Sam Raimi.

Kunis is on board as Theadora, a witch who falls for Franco. Rachel Weisz is in talk to play sister Evanora, the evil witch who wants to rule the land and tries to seduce Theadora to the dark side; Weisz’s dealmaking is complicated due to her having an offer to star opposite Jeremy Renner in Universal’s new Bourne movie, and shooting schedules would overlap.

If a deal makes for Williams, she would play a powerful witch who teams up with Franco to defeat  Evanora (and maybe Theadora, but we’re not revealing spoilers).

Oz centers on Franco as a snake oil salesman who finds himself dealing with real magic when his balloon carries him into a fabled land and he runs into genuine witches.

Williams, repped by CAA, last year wrapped  production on Sarah Polley’s Take this Waltz, also starring Seth Rogen.  The movie is being shopped in Cannes.
