'Once Upon A Time' Season Four Spoilers - Hit ABC Show Gets Even Colder, Adds Two More 'Frozen' Characters To Cast

Get ready for even more of your favorite Frozen characters to join the cast of Once Upon a Time.

Creators of the show have revealed that Elsa won't be the only one coming to the shores of Storybrook from the kingdom of Arendelle, when the hit series returns to ABC this fall. E! News has learned that the show is currently casting the roles of both Anna, and Kristoff, voiced by Kristen Bell and Jonathan Groff in the animated movie.

The gossip site reports that they characters will stay true to their animated counterparts, so die hard fans of the film can heave a sigh a relief.

The story seems like it will pick up a little bit after the events of the film, because it has been revealed that when we first meet Kristoff he will be adjusting to his new life in Arendelle alongside Anna and Elsa. Elsa and Anna are both described as valuing their relationship with one another above all else.

All three characters are set to recur in a number of episodes during the show's fourth season.

When E! caught up with Adam Horowitz after the finale last month, he revealed a few details about what he plans to do with the Frozen storyline.

"Well, it's funny, we're not going to redo the movie, because we just don't feel like it's in anyone's interest for us to redo it, but what we are going to do, we're not ready to tell you. What we can say is we're very aware of what we think makes this character from Frozen so special and we want to honor that and make sure that what we do is in the universe of everyone fell in love with this past year."

As far as casting for the two additional roles, Bell did say that she would definitely be up for reprising her role of Anna, should producers want to include her.

No news yet, on who will play Elsa or Kristoff, but if it does end up being Idina Menzel and Jonathan Groff we definitely won't be complaining.
