Once Upon a Time Casts Its Elsa

Georgina Haig will play the role of Elsa—as in, Frozen‘s snow queen—in the upcoming season of Once Upon a Time, ABC said Thursday.

Haig has previously appeared in the movie The Sapphires and, as Etta, in the TV show Fringe.

The news that Elsa would appear in the fairytale-centric show made a splash in May when a suspiciously similar looking woman appeared in the show’s season finale. At the time, executive producer Edward Kitsis told TIME the mysterious new character was definitely Elsa but that the actress who would play the newly-beloved Disney character had not yet been cast. The idea to include the character had been brewing for months, as it became clear that popular love for Frozen was not just a passing fad.

Frozen characters Anna and Kristoff will be played by Elizabeth Lail and Scott Michael Foster.
