Who do 당신 think can portray Elsa in live action? Rumour has it OUAT producers want the sisters in s4 OUAT.

definitely Elsa (not because of that!) Hosk, if she can act.

but since TV prefers 인기 actors to accurate ones and they don't mind changing the characters (cough Aurora), she may not be blonde and blue eyed at all. so who knows?
