Idina Menzel sings her lungs out in Disney’s glossy cartoon update of The Snow Queen.

Disney gives Hans Christian Anderson’s chilly fairytale a glossy, girl-power makeover with this hit animated musical – a $1billion global blockbuster that bagged Oscars for Best Animation and Best Song.

The studio’s take on the story turns it into a tale of two orphaned princesses – chirpy optimist Anna (Kristen Bell) and her tormented sister Elsa (Menzel), who flees into self-imposed exile after her icy powers cast her kingdom into eternal winter.

Anna’s snowy quest to save her sibling – helped by hunky ice merchant Kristoff (Jonathan Goff) and his reindeer Sven – is accompanied by enchanting visuals and show-stopping tunes.

Big-lunged Broadway diva Menzel claims the film’s vocal honours with her rousing Oscar-winning ballad Let It Go, but stealing the movie outright is comic relief Josh Gad’s winningly goofy talking snowman – who is too dim to realise that longing for the arrival of summer is not particularly wise for one of his kind.
