“Once Upon A Time” has officially been “Frozen” over.

The ABC fantasy drama cast its first two live-action characters from Disney’s “Frozen” earlier this week, with “Greek” alum Scott Michael Fost as Kristoff and newcomer Elizabeth Lail as Anna. Now the network has finally cast the most anticipated role of Queen Elsa of Arendelle. Georgina Haig, best known as Etta Bishop from “Fringe,” will play the character voiced by Idina Menzel in the Disney film.

Queen Elsa was first teased at the very end of “OUAT” Season 3 when she briefly appeared with her icy powers. In the upcoming season, the “Frozen” storyline will take place following the events of the film.
