Michelle Williams: Summer Stroll in Tribeca

Michelle Williams heads to the Tribeca Film Center’s office building for a meeting on Friday (July 15) in New York City.

The 30-year-old actress next will be working on Disney’s Oz, the Great and Powerful, the Sam Raimi-directed flick with James Franco, Rachel Weisz, and Mila Kunis.

The three ladies will play powerful witches Oz runs into when his hot air balloon carries him into a fabled land.

THR also reports that Mad Men‘s Abigail Spencer has joined the film’s cast.

She’ll take on the role of “a young woman who is a willing subject of Oz’s magic tricks, which the erstwhile magician is performing in Kansas.”
