Disney’s 'Frozen' revitalized the animated musical blockbuster in the 21st century. While Disney had many hits, 'Frozen' became a cultural phenomenon due to its subversion of classic princess tropes (focusing on sisterhood rather than romance) and its hit song 'Let It Go.' The film earned over $1.2 billion and remained in theaters for months. The soundtrack was a massive success, spending 13 non-consecutive weeks at #1 on the Billboard 200. This multi-media success (film, music, and merchandise) proved that the classic Disney musical formula, when updated for modern sensibilities, could still produce the world's biggest blockbusters.
