Season 4 of television's much-awaited fairy tale extravaganza will soon return, and the producers revealed many details on what's going to happen in season 4 of Once Upon A Time.

The ABC hit Once Upon A Time has gotten both children and adults excited for its next season, and the show's producers are making sure that the series will live up to the hype. Adam Horowitz and Eddy Kitsis talked to Entertainment Weekly about their plans for season 4.

When asked about the inclusion of Frozen characters into the show, Kitsis recalls how the writers loved the movie and it was an easy decision to make.

"We saw the movie, and collectively, the whole entire writers' room just loved it. It was our favorite film. What we loved so much about Elsa was she was perceived to be a villain, but of course we understood she was misunderstood. And the only one who understood that was her sister. That was a very thematic thing for us, which is a misunderstood character who everyone perceives to be bad," said Kitsis in the Entertainment Weekly interview.

The show runners said that Elsa won't be the only Frozen character that viewers will see in the next season. Speculations arise when Horowitz and Kitsis revealed that they are fond of Olaf the snowman.

"We'd be disappointed if Elsa was the only one we saw, but we're not quite ready yet to tell you who else we may encounter," said Horowitz in the same interview.
