'Once Upon A Time' 'Frozen' Storyline: Elizabeth Mitchell, Of 'Lost,' 'V,' To Play Villain Snow Queen

While Once Upon a Time might have just premiered its fourth season last Sunday, it seems fans can't seem to get enough of the Frozen storyline. Well, we have a major scoop for viewers about the villain for the first half of the season's storyline. It has been speculated that Lost and V alumna Elizabeth Mitchell would be bringing the Snow Queen to life, but the creators have been keeping tightlipped on the actress's involvement on the ABC series.

But fans are in luck today, as the first pictures of Mitchell on the show's set have been released, thanks to The Daily Mail.

From the photos we can see Elizabeth in a regal, all-white gown, looking every bit as wicked as the character she is set to play. Creators Edward Kitsis and Adam Horowitz spoke to Entertainment Weekly, where they let some details about the role slip out.

While many fans were anxious that Elsa would be cast on the show as the villain for this season, Kitsis immediately put us at ease, saying, "What Elsa's motivation will be will be revealed in the premiere, and I don't want to spoil it, but I can tell you that she won't be a villain."

So with the villain set empty for this season, the creators do tease that viewers will be soon introduced to the Snow Queen, who is being played by Mitchell.

"What we can say about Elizabeth on the show is that for the first time, we're showing a villainous side to Elizabeth Mitchell," the creators, who have worked with the actress on V and Lost, explained. "Not just working with the Others because she has no choice, but a truly villainous side. We can't wait to scare everyone."

We can't wait to be scared. An all-new episode of the magical series premieres tonight at 8 p.m. on ABC.
