Former “Mad Men” starlet Abigail Spencer is heading down the yellow brick road to partake in director Sam Raimi’s Wizard of Oz prequel Oz, the Great and Powerful. Joining her on that journey are James Franco and hotties Rachel Weisz, Michelle Williams and Mila Kunis.

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.

Heat Vision exclusively reports that Spencer will play “a young woman who is a willing subject of Oz’s magic tricks which the erstwhile magician is performing in Kansas.” Filming is set to begin later this month in Michigan.

Spencer, best known for her portrayal of Don Draper cock-accessory Suzanne Farrell on AMC’s “Mad Men,” will be seen later this month in DreamWorks’ Cowboys & Aliens. The pretty 29-year-old will also star opposite Katee Sackoff in the Lionsgate sequel A Haunting in Georgia.
