NEW YORK (Bloomberg) - Walt Disney tapped Frozen film-maker Jennifer Lee to become chief creative officer of its namesake animation studio, setting a new course for the business after the departure of disgraced visionary John Lasseter.

As part of the reshuffling, Pete Docter - director of Up and Monsters Inc. - was also tapped to take over the same role at Pixar Animation Studios.

Lee, 46, and Docter, 49, will have creative oversight of all films and associated projects of their respective studios and report directly to Mr Alan Horn, chairman of Walt Disney Studios.

The move brings two Academy Award winners into key roles following the ouster of Lasseter earlier this month. The 61-year-old was the creative force behind Pixar and Disney Animation until allegations of inappropriate workplace conduct led the company to part ways with the executive.

He continues to consult on films, but will stop working for the studio at the end of the year.

The move also thrusts a woman into one of the highest-profile studio roles in Hollywood. Lee co-directed Frozen, which remains the highest-grossing animated film of all time.

Pixar is fresh from a massive box-office win this weekend with Incredibles 2.

The movie posted the best-ever opening for an animated film, helping ease Disney's pain from its disappointing Solo outing earlier this year.
