Who Could Play Frozen's Elsa on Once Upon a Time?

1 Blake Lively

The Gossip Girl star hasn't ventured back to TV yet, but Lively has the perfect look for the role. She basically auditioned when she wore this braid.

2 Maggie Grace

Once Upon a Time's cocreators, Edward Kitsis and Adam Horowitz, also produced Lost, and they've brought in old cast members to their new show many times over. Emilie de Ravin, Jorge Garcia, and Rebecca Mader have all appeared on OUAT, so we wouldn't be surprised if Grace popped up next.

3 Idina Menzel

This is a long shot, but Menzel, who voiced Elsa in the animated film, would be perfect to step into the role in real life. She has said she'd love to play Elsa on Broadway, so with a convincing blond hairstyle, it could work. Bonus points if she needs to sing.

4 Claire Holt

On The Originals, Holt's character Rebekah can be downright cold, but she will also do anything for her siblings and cares for others deep down. Sounds just like Anna and Elsa's relationship to us.

5 Dianna Agron

With a long, braided wig, Agron could transform into Elsa immediately. On Glee, her character Quinn closed off to keep from getting hurt, and, of course, she also sang!

6 Megan Hilty

Hilty definitely has the pipes to pull off Elsa's role, and she also has already played a character who comes off cold but has a warm heart deep down. RIP, Smash.
