When creators announced that "Once Upon A Time" season 4 would be an adaptation of the wildly popular Disney animation, "Frozen," fans of the movie grew apprehensive for the casting.

Since the characters were so beloved by a wide age-range, looking for the best people to play Princess Anna, Queen Elsa, Kristoff, and Prince Hans became very crucial.

"Once Upon A Time" season 4 producers, Adam Horowitz and Edward Kitsis, promised to keep the casting as close to the film as possible. Why? Well, "simply because what happened in the film was so beautiful."

So far, the roles have been filled with the exception of Prince Hans. E! News reports that the thirteenth in line to the Southern Isles could be the possible villain in the story.

"Once Upon A Time" season 4 would still have Ginnifer Goodwin (Snow White) and Josh Dallas (Prince Charming) but the frozen cast will be added on to the mix.
