As "Once Upon a Time" goes on hiatus before season 4, the search for a perfect Elsa has spread to social media.

Amidst a slew of fantasy celebrity casting for "Once Upon a Time" season 4, 18-year-old Anna Faith Carlson is using Instagram to make a case for being the perfect Elsa.

I know this is kind of a lot to ask, but it would mean the world to me," wrote Anna on Instagram. "Can you take a picture from my page dressed as Elsa, post it and hashtag the worlds #AnnaAsElsa? I'm hoping to audition as Elsa on 'Once Upon a Time!'"

Since her campaign, Anna has garnered quite the social following, although whether it translates to being Elsa on "Once Upon a Time" season 4 remains to be seen.

“If I got an audition, I could show them two sides of Elsa. On 'Once Upon A Time' she was a bit of a villian, but I could show her other side — that she’s trying to protect everyone. I have a couple skits I could show them — and I could sing, too!”

But, "no one from ABC has contacted me yet."

Meanwhile, spoilers have emerged regarding Emma and Hook on "Once Upon a Time" season 4.

"There will be some challenges for them," said co-creator Adam Horowitz according to TVLine.

“The very first obstacle is Emma’s guilt over the fact that she just destroyed Regina’s relationship [with Robin Hood],” added Eddy Kitsis. “So there’s a part of her that feels guilt in starting a new romance of her own.”
