Elsa is famous for her transformation, and now she will be taking on a completely different form when she steps into the world of Storybrooke on ABC’s Once Upon A Time. A live action version of Elsa was glimpsed at the end of the third season finale by way of introduction. Producers Eddy Kitsis and Adam Horowitz have confirmed that she will have her own storyline in season four as a woman "misunderstood" and sometimes perceived as a villain, according to The Hollywood Reporter.
Once Upon a Time usually adapts characters from ancient fairy tales, but this time they are going outside the box with a completely contemporary queen from Disney’s Frozen rather than the more than century-old counterpart, the Snow Queen from Hans Christian Andersen. The producers fell in love with Elsa after watching Frozen four times, and it was their idea to ask Disney for permission to include her on the show. Plenty of oversight will happen, including by Disney and ABC, to make sure that Elsa remains true to her Frozen origins.
The next big question is who will play her. The producers are taking a much-needed vacation, but immediately after Memorial Day they will get to work on the difficult task of casting Elsa.
