The Frozen franchise will set a new Disney Princess movie record with the upcoming release of Frozen 3, and it's only going up from there. Upon its release in 2013, Frozen was one of Disney's biggest organic hits in years. The icy tale of two distant sisters explored themes like isolation, betrayal, companionship, and self-acceptance, while subverting tons of traditional Disney Princess tropes, like the lead being saved by true love. Frozen became a cultural phenomenon and spawned a whole Frozen franchise, including a sequel.
