IT director Andy Muschietti explains how his movie evolved from Cary Fukunaga and Chase Palmer’s original script.
Unfortunately, the studio had migrated IT over to their sister studio, New Line Cinema, and subsequently cut the movie’s budget.
New Line Cinema hired Andy Muschietti (Mama) as Fukunaga’s replacement later that year, with the director’s sister, Barbara Muschietti, serving as producer.
In an interview with Collider, Muschietti explained how they used Fukunaga and Palmer’s script as a “basis” for their movie.
