Actress Mila Kunis has confirmed a sequel to Oz The Great And Powerful is in the works.

Disney bosses have given the green light for a follow-up, which would continue the adventures of Oz, played by James Franco in the fantasy film.

Kunis, who plays Theodora, one of three witches, tells, "We're all signed on for sequels," while Michelle Williams, who stars as Glinda the Good Witch, adds, "Wherever Sam (Raimi, director) goes, I'll go. I'd do anything Sam asks me to do. I'd get stuck in quicksand with him."

According to The Hollywood Reporter, scriptwriter Mitchell Kapner has been tapped to pen the next installment.
