Rachel Weisz is in talks to join the cast of Sam Raimi’s upcoming Wizard of Oz prequel. She’d play Evanorah, older sister to Mila Kunis’s Theadorah and eventual Wicked Witch of the East. Oz, The Great and Powerful follows James Franco’s Wizard as he battles the dangerous sisters. Yet to be cast? The good sister, Glinda. Brunettes, call your agents! [Heat Vision/HR]
