NBC's The Wiz Live! has found its Dorothy.

Newcomer Shanice Williams, an 18-year-old musical theater actress from New Jersey, has been cast in the lead role for the upcoming live musical, which will air on Thursday, Dec. 3. She beat out hundreds of other girls who auditioned for the part.

The Wiz is an adaptation of The Wizard of Oz that features the Wicked Witch of the West, seeking to avenge the murder of her evil sister, kidnapping Dorothy and her friends in order to steal the slippers that were given to Dorothy by the Good Witch of the North. It opened on Broadway in 1975, and a film adaptation starring Diana Ross, Michael Jackson and Richard Pryor was released in 1978.

The Wiz Live! is being executive-produced by Craig Zadan and Neil Meron, who also produced NBC's previous live musical events, The Sound of Music and Peter Pan.
