Frozen review – Disney's thrilling but occasionally gluggy stage musical won't let audience go Cassie Tongue Disney unleashed Frozen onto the world in 2013. Inspired by a fairytale – it’s loosely based on The Snow Queen – Jennifer Lee’s script about sisterly love, sacrifice and loneliness (OK, it’s still Disney: there’s also a talking snowman who’s obsessed with summer) was an instant hit. It was lifted higher by spare but affecting songs, the jewel of which is the anthemic Let it Go by Robert Lopez and Kristen Anderson-Lopez. Frozen is the 16th highest-grossing film worldwide; it was the best-selling musical in the United States (now only surpassed by its own sequel and the 2019 live-action remake of Aladdin).
