Tim Gray Senior Vice PresidentThe team behind Disney Animation’s “Encanto” gave themselves a high degree of difficulty: In a development/production process that took five years of constant rewrites, they insisted on a film with a family of 12 principals, while most animated films center on half that number.The film is about 15-year-old Mirabel Madrigal (voiced by Stephanie Beatriz) and her family; the breakout star for fans and social media is Bruno, the exiled uncle voiced by John Leguizamo. “Encanto” was written by Jared Bush and Charise Castro Smith from a story credited to six writers, including those two.
