James, 25, plays Cinderella in this retelling of the classic story about a servant step-daughter who wins the heart of a prince. And you'll be happy to learn that those glass slippers are "really comfortable," according to Ella's Fairy Godmother.
One of the sweeter lines in the trailer comes from Cinderella's late mother (Hayley Atwell) who gives her daughter some advice before she leaves her. "Have courage, and be kind," she says. "Where there is kindness, there is goodness and where there is goodness, there is magic."
