Furiosa: A Mad Max Saga hasn't hit theaters yet, but its director, George Miller, has already been spitballing ideas for the character's next chapter in the franchise. Starring Anya Taylor-Joy as the eponymous heroine, Furiosa is a prequel to 2015's Mad Max: Fury Road, and shows her journey from a child of the 'Green Place' to the shaved-headed killer audiences adored in Miller's long-awaited return to the franchise.
