It’s a rare treat to be able to sit down with two of the towering figures of pop music and film music to talk about a collaboration for film. In this case it was songwriter-producer Pharrell Williams and top Hollywood composer Hans Zimmer — along with their friend and musical colleague Benjamin Wallfisch. The three of them produced the score and songs for the new film Hidden Figures, the remarkable untold story of three African-American women were part of the American space program in the early 1960s. Williams served as one of the film’s producers and wrote the songs, which in turn inspired the score penned by Zimmer and Wallfisch. It has an undeniable ’60s vibe infused with gospel sounds, and this story for Variety‘s Music for Screens issue discusses their collaboration.
