Before Queen Elsa casts her icy spell on Once Upon a Time‘s upcoming fourth season, the powers that be need to do some casting of their own.
Showrunners Adam Horowitz and Eddy Kitsis have confirmed to TVLine that Frozen‘s ice queen indeed arrived in Storybrooke at the end of Sunday’s finale, but her portrayer still remains a mystery, even to them.
Should it be another former Lost star, like Maggie Grace or Elizabeth Mitchell? Perhaps a teen drama vet, like Gossip Girl‘s Blake Lively or Glee‘s Dianna Agron?
