Following the sneak peek released earlier this week, Disney this morning unveiled the first full-length trailer for director Kenneth Branagh's full-length retelling of Cinderella.

Written by Aline Brosh McKenna (We Bought a Zoo) and Chris Weitz (The Twilight Saga: New Moon), this version stars Downton Abbey's Lily James as Ella, who refuses to lose her courage, despite the torments of her stepmother and stepsisters. You probably already know the rest of the story. If not, the trailer will fill in the gaps.

Opening March 13, Cinderella also stars Cate Blanchett, Richard Madden, Helena Bonham Carter, Sophie McShera, Holliday Grainger, Anastasia Tremaine, Stellan Skarsgård, Hayley Atwell, Ben Chaplin, Derek Jacobi and Nonso Anozie.
