Walt Disney Animation Studio’s latest princess movie is like a multi-million dollar musical snow globe come to life. It’s set in the gloriously detailed, picture-perfect fjord town of Arendelle, with two wide-eyed, porcelain-skinned princess sisters and a catchy singsong soundtrack by award-winning Broadway composers. When shaken up in 3-D, it conjures marvellous aurora borealis skies and exhilarating blizzards. If it isn’t snowing where you are already, there’s really only way to watch this film—with the air conditioner on full blast.
