Disney's Frozen (2013) is arguably the most successful animated film of all time. It's in the works for the third installment, and a fourth was just announced by the studio. Its title song, Let It Go, became the unofficial anthem of the year upon its release. And it spawned multiple short films, countless merchandise opportunities, a Broadway show, and even a documentary on Disney+ about the making of its sequel, Frozen II (2019). Disney most certainly won't be putting one of their most lucrative intellectual properties to rest anytime soon.
