As Cinderella was going to face the prince and try on that legendary glass slipper, the narrator—her fairy godmother—said to the audience, “Would who she was really be enough? She had no magic to help her this time. It was perhaps the greatest risk of all. To be seen as you truly are.”
Update 8 April 2015:
I've seen the movie for the second time. Still loves it, still pleasantly surprised with the twist. Also, I noted that the fairy godmother narrated the scene where Cinderella came down from the attic to fit the shoe as such:
"Would who she was, who she really was, be enough? There's no magic to help her this time. This is perhaps the greatest risk that any of us will take: to be seen as we truly are."
Just love it...(might go for the third time).
Also, have seen Frozen. Love it. But I still love the Beauty and the Beast the most for the animated version. For the live-action, Cinderella 2015 is definitely on top of my list.
