Walt Disney Animation Studios is replacing Jennifer Lee, its chief creative officer, after an uneven six-year tenure.

Frozen II was the last big hit that Disney Animation had. The pandemic would follow shortly after its release. Raya and the Last Dragon was released while many theaters were still closed. Encanto, Strange World, and Wish were all disappointments at the box office, though Encanto would find new life on Disney+.

Lee is writing and directing “Frozen 3” and writing “Frozen 4” with Marc Smith — the sequels to Disney Animation’s 2013 “Snow Queen”-inspired cultural hit “Frozen,” for which she served as writer/director. The movie made $1.3 billion worldwide and earned two Oscars, for best animated feature and for earworm song “Let It Go.”
