As soon as it was revealed that Elsa, from Frozen, was set to become a character in ABC/Disney's series Once Upon a Time this fall, it seemed inevitable that we'd learn her sister Anna would be joining the series as well. Now, TVLine have confirmed that is indeed the case.

"Let it... dang it, I forget the next word!"

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 (in which instance Vancouver weather could rival Winnipeg’s!)



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.

Not only will Elsa & Anna be a part of the show, but Kristoff will be, bringing at least three characters from Disney's massively successful animated film -- now the fifth highest-grossing movie ever, worldwide -- into the live-action world of Once Upon a Time.Elsa, who was already glimpsed in the Season 3 finale -- albeit by a stand-in, as final casting had not been done yet -- will appear in approximately nine episodes according to TVLine, with Anna and Kristoff appearing "a bit less."TVLine also have the character breakdowns for all three characters, as the hunt begins for the actors to play what are sure to be much-desired roles, given Frozen's incredible popularity (the movie just finished it's thirteenth week at number 1 in Japan!).Who wants to bet ABC hope to have the casting for Elsa & Anna locked down by Comic-Con, to have the actors present for the Once Upon a Time panel?
