This marks another shakeup in Pixar’s leadership in recent years. Back in November 2017, the former chief creative officer of Pixar and Walt Disney Animation Studios, took an extended leave of absence following reports of him engaging in sexual misconduct and inappropriate behavior, and by the following July, he announced he would leave Disney at the end of the year. Lasseter has since been hired to be the head of Skydance Animation. Ed Catmull, one of Pixar’s co-founders, also announced last fall that he’s retiring from Disney/Pixar, though he’ll stay as a consultant until July.
