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.

As Disney readies the sequels to its uber-grossing $1.75 billion Frozen franchise, Walt Disney Animation Studios Chief Creative Officer Jennifer Lee is segueing from her position to direct and write Frozen 3 and pen Frozen 4 with Marc Smith.
