Georgina Haig, who is on "Reckless" and played Peter and Olivia's daughter on "Fringe" will be taking on the roll of Elsa from "Frozen" on "Once Upon a Time," according to TVGuide.com.

As we all saw in the season finale, the Queen of Arendelle was let free from Rumpelstiltskin's vault in the past and came to the present. We saw the icy entrance and all are wondering whether she will be the new big bad for season four.

Now executive producers Adam Horowitz and Edward Kitsis have said that "Frozen's" Elsa is misunderstood and has never been a villain. That doesn't mean she won't wreak a little havoc in Storybrooke until things are settled.

Playing her little sister Anna is newcomer Elizabeth Lail and playing her love interest Kristoff is Greek alum Scott Michael Foster, according to Entertainment Weekly.
