Australian actress Georgina Haig has officially been cast as Once Upon A Time’s Queen Elsa from Frozen.

Georgina Haig Cast As Elsa

Executive producer Adam Horowitz welcomed Haig, best known for her role as Henrietta ‘Etta’ Bishop on the last season of Fox’s Fringe, to the show on Twitter.

Once Upon A Time introduced the magical Queen, who has power over the weather, most notably the cold, in the series’ third season finale. The viewers were treated to a glimpse of Elsa and her powers as she arrived in the fairy tale town of Storybrooke, but a stand-in was used to portray the role, as Elsa had yet to be cast.

'OUAT' Will Feature Elsa After The Events Of 'Frozen'

Horowtiz had previously refused to divulge any details on Elsa’s OUAT character – whether her journey on the show would follow the events of the hit animated film or be an entirely different storyline. Now, TVLine has learned that when Elsa comes to Storybrooke in Once Upon A Time, it will have followed the events of Frozen, in which Elsa accidentally unleashed an eternal winter on her kingdom, Arendelle, before learning that the love of her sister, Anna, helps her channel her powers.

“We are very well aware of how beloved [Frozen] is, so we’re very careful that we want to tell a story that is uniquely ours but also honors those characters that everyone fell in love with this past year,” Horowitz told TVLine.

Co-executive producer Edward Kitsis added, “The thing we love about Elsa is she is perceived to be a villain but is clearly misunderstood, and that goes to the heart of our show.”

The announcement that Haig will be playing Elsa in OUAT’s upcoming forth season comes on the heels of the casting of two other characters from Frozen set to make an appearance. Elizabeth Lail and Michael Scott Foster have been cast as Elsa’s sister, Anna, and Anna’s love interest Kristoff, respectively. Foster is expected to appear in around six episodes, while Lail will be featured in six to eight episodes and Haig is said to be in nine episodes.
