Jennifer Lee has stepped down as Chief Creative Officer of Walt Disney Animation Studios to focus on writing and directing the 'Frozen' franchise, specifically 'Frozen 3' and 'Frozen 4'. She has been succeeded by Jared Bush, who has been a prominent creative force at Disney for over a decade and won an Oscar for 'Encanto'. Lee's departure comes amid a challenging period for Disney's animation division, which has faced several box office disappointments, although she oversaw significant successes like 'Encanto' and the original 'Frozen'. Bush, who will also direct 'Zootopia 2', expressed his excitement to lead the studio and work with its talented team. Lee thanked Disney leadership for their support and looks forward to her return to filmmaking. The transition is part of Disney's ongoing efforts to improve movie quality and adapt to changing audience preferences.
