The great composer-songwriter Randy Newman was my guest at a screening of Marriage Story sponsored by Netflix on Friday night at the iPic in Westwood. During a wide-ranging 45-minute conversation, we discussed his second collaboration with director Noah Baumbach (after 2017’s The Meyerowitz Stories); the orchestral music he wrote for the searing depiction of a divorcing couple (played by Scarlett Johansson and Adam Driver); a bit about his Toy Story 4 score; and rumors that a documentary is being made about his life and career.
