Once Upon a Time Season 4 Spoilers: Elsa From ‘Frozen’ to be Joined by Anna and Kristoff on ‘OUAT’

Elsa isn’t the only character from “Frozen” that will appear in Once Upon a Time season 4.

She’ll be joined by her sister Anna and Kristoff, the ice merchant.

There’s been rumors that Olaf, the snowman, will show up–but no confirmation as of yet.

Elsa will appear in approximately nine episodes while her sister and Kristoff will appear in almost as many, according to TVLine.

The characters in the animated movie were voiced by Idina Menzel, Kristen Bell, and Jonathan Groff.

Casting for all three for “OUAT” is taking place now, with at least Bell reportedly under consideration for the real-life version.

Leading actresses for the role of Elsa include Elizabeth Mitchell, Maggie Grace, and Hillary Duff. There’s been no insight yet into who could play Kristoff.

Show co-creators Eddy Kitsis and Adam Horowitz said previously that Elsa would have a twist but stay true to the essence as presented in “Frozen.”

“For us, I think this is Elsa from Frozen. That was kind of the inspiration… Will there be our own elements put to it? Yes. Like all things like we do with Snow White or Peter Pan or Captain Hook, we take our own kind of twist on it but remaining faithful to the actual essence of the character,” they told Entertainment Weekly

The creators also said that Elsa and Rumplestiltskin know each other, but didn’t specify how.

Chek out the character breakdowns from ABC, via TVLine.

“ELSA | The Queen of Arendelle, this late-20s/early-30s beauty long struggled to control her “chilling” powers and even unleashed upon her town an eternal winter during her coronation. Ultimately, she realized that the key to controlling her powers is love — namely, her bond with sister Anna — and now she is aware of the threat she poses if she were to lose control of her magic again.

“ANNA | Elsa’s slightly younger sister is a fun-loving, fearless optimist who often gets herself into situations where she is in over her head, yet is able to triumph due to her resourcefulness and can-do spirit. She values her relationship with her sister above all else.”

“KRISTOFF | This handsome, hearty, salt-of-the-earth ice cutter spent most of his life alone (unless you count his reindeer). He has a sometimes-gruff demeanor that can hide his deep love for Anna and her sister Elsa. When we first meet Kristoff on Once, he is adjusting to life at the castle — including sleeping indoors for the first time in his life.”
