If you have seen Frozen 2, then you’ll maybe remember that there is a voice that calls to Elsa throughout.
Some audience members were convinced that it was Elsa’s mother. Others argued that it was actually her own voice that Elsa heard-
But Disney has confirmed, that “the voice is the mother.”
Kids are really serious about their Frozen movies, so if you have a youngster, make sure they know whose voice Elsa was hearing during the second film.
