The first trailer for Disney’s “Cinderella” has arrived at the ball. Starring Lily James (“Downton Abbey”) as Cinderella and Cate Blanchett as her wicked stepmother, the new version of this classic fairytale keeps things old school: there’s a fairy godmother (played by Helena Bonham Carter), a pumpkin carriage, a blue dress and Robb Stark the handsome Prince Charming (played by “Game of Thrones” vet Richard Madden). Kenneth Branagh directs. “Cinderella” is out on March 13, 2015.
