Staff WriterFrozen-related storyline! What we already know about that episode revolves around the fact that Frozen’s main character, Anna, is going to be played by Elizabeth Lail and Elsa will be portrayed by Georgina Haig, whom we know from Fringe. Mitchell has played in the much loved show Lost, V and Revolution. She is now possibly set to play a villain for the first time, which sure is exciting. We are not yet told the exact storyline for season 4, but apparently it is said to take place after everything we already know from the Oscar-winning Disney movie. Are you excited for the new plot for Once Upon a Time? Will you be watching Mitchell rock her part? Be sure to let us know in the comments! Keep Up With PopWrapped On The Web!
