John Williams is one of Steven Spielberg’s most frequent collaborators, and earlier this year he was set to score both of the director’s upcoming movies: Pentagon Papers drama The Papers and pop culture-infused sci-fi Ready Player One. But because both of these movies are being put together at about the same time (Ready Player One’s production began last year, and The Papers was filmed this spring in a matter of weeks for a December release) Williams has had to give up scoring duties on the latter in favor of the former.
