The film stars Helena Bonham Carter as the Fairy Godmother, Cate Blanchett as the wicked stepmother, Lily James in the title role and Richard Madden as the prince.
New Years Eve seemed like a logical enough place for them to debut some footage, since in-story, Cinderella's world changes when the clock strikes midnight.
You can see the trailer below, along with Disney's official synopsis.
The story of Cinderella follows the fortunes of young Ella (Lily James) whose merchant father remarries following the death of her mother. Eager to support her loving father, Ella welcomes her new stepmother (Cate Blanchett) and her daughters Anastasia (Holliday Grainger) and Drisella (Sophie McShera) into the family home. But, when Ella's father unexpectedly passes away, she finds herself at the mercy of a jealous and cruel new family. Finally relegated to nothing more than a servant girl covered in ashes, and spitefully renamed Cinderella, Ella could easily begin to lose hope. Yet, despite the cruelty inflicted upon her, Ella is determined to honor her mother's dying words and to "have courage and be kind." She will not give in to despair nor despise those who mistreat her. And then there is the dashing stranger she meets in the woods. Unaware that he is really a prince, not merely an apprentice at the Palace, Ella finally feels she has met a kindred soul. It appears her fortunes may be about to change when the Palace sends out an open invitation for all maidens to attend a ball, raising Ella's hopes of once again encountering the charming Kit (Richard Madden). Alas, her stepmother forbids her to attend and callously rips apart her dress. But, as in all good fairy tales, help is at hand, and a kindly beggar woman (Helena Bonham-Carter) steps forward and – armed with a pumpkin and a few mice – changes Cinderella's life forever.
