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.

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.”
