The show creators showed a short preview of the upcoming season. The reported video will not be distributed widely yet. Georgina Haig and Elizabeth Lail will play Elsa and Anna, respectively.

In the video, Elsa and Anna were seen visiting their parents' grave and they placed flowers on the grave. In the movie version, it was shown that their parents died at the sea. It seemed that the small screen will start after the incident. Suddenly, Elsa tells her sister, "Anna, they would be so proud of you." She added that she has a surprise for her sister for her upcoming wedding. Anna and Kristoff are tying the knot.

The fourth season of "Once Upon A Time" will come back on air on September 28 featuring beloved characters in "Frozen".

Fans of the hit ABC TV series went crazy after Queen Elsa was shown in the last two minutes of the final episode of "Once Upon A Time" season 3. Right now, the show creators and executive producers Edward Kitsis and Adam Horowitz confirmed that Elsa, Anna and Kristoff will definitely appear in show next season.

However, it is most likely that fans will not see the cute snowman Olaf, which is one of the beloved characters in the Disney movie.

"Once Upon A Time" spoilers claimed that Queen Elsa will be back in her original state being a villain in the story. The TV series is known for twisting the original version of our beloved childhood fairy tales and turning the main characters into villains. Thus, it was speculated that if the next season will be based in the Disney movie, this will most likely happen.
