In an interview published in the Official Disney Fan Club magazine, director Steven Spielberg shared details on making The BFG, including working with John Williams on the film’s score:
In terms of the movie’s music, it’s no surprise that Spielberg would turn to his longtime collaborator John Williams, a five-time Oscar winner who has scored most of Spielberg’s films since 1974. “I will tell John my story by showing him my cut and he goes away and eight weeks later, he tells a story musically,” Spielberg explains. “He has done this brilliantly with ‘The BFG.’ Every moment is accompanied by a little bit of a musical reminder that there is another layer of story being told.”
