Loads of constructive criticism:
Pixar’s secret? Its unusual creative process. Most of the time, a studio assembles a cast of freelance professionals to work on a single project and cuts them loose when the picture is done. At Pixar, a staff of writers, directors, animators, and technicians move from project to project. As a result, the studio has built a team of moviemakers who know and trust one another in ways unimaginable on most sets.
Which explains how they can handle the constant critiques that are at the heart of Pixar’s relentless process.
