Disney planning Frozen television crossover

After saying that they weren't interested in rushing into a sequel, Disney has announced that the characters of Frozen will be crossed over into their fairly successful television show Once Upon a Time. This is known because Elsa was teased at the end of the season three finale last night. You can see it below.




Showrunners Adam Horowitz and Adam Kitsis insist that the inclusion of Elsa was entirely their idea because they loved Frozen so much and their kids love it. They also do mention that the portrayal in the show will be their take on the character so that isn't a guarantee that she will be the same. I will say up front that I don't watch Once Upon a Time, but judging from this clip it looks like they might be going to villain route for Elsa.
Casting for Elsa is not completed yet so that pretty much means they used a random body double for the clip. Filming for season four begins later this month, so I'm sure people will find out who will be playing Elsa before too long.

Once Upon a Time isn't necessarily a critically acclaimed show and it is more popular among Disney fans than anyone else, so this might simply be a marketing draw to try and gain new viewers. The overall popularity of Frozen makes it an easy target for exploitation.
