As well as picking up Academy Awards for best animated feature and best original song, plus a Bafta, a Golden Globe and five Annie Awards, Frozen is an eye-watering commercial success. Already the UK and Ireland’s highest grossing original animated film of all time, it has also passed the global $1 billion dollar mark – the first Disney animation to do so. It has even leapfrogged Toy Story 3, which took $1,063.2, to become the world’s highest grossing animated film of all time. And when the film eventually leaves cinemas, Disney has little to worry about; pre-orders of the DVD and Blu-Ray made it Amazon's bestselling children's film of all time before it was even released in the US. And when it was, it sold 3.2 million units on its first day (including pre-sales).The soundtrack, meanwhile, beat Beyonce’s surprise December album to the top of the Billboard chart, and has since been streamed over 7.5 million times on Spotify. There’s also a Broadway musical in the works.
