In a huge and completely unexpected movie, Disney has announced that effective immediately Jennifer Lee is stepping down as CCO of Walt Disney Animation Studios. She will return to filmmaking as the writer and director of Frozen 3 and will co-write Frozen 4.

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.”

Lee is stepping down as Disney's animation chief and will return exclusively to filmmaking.
