Movies delight and inspire and repel. They’re places the big questions we take up at On Being land in the heart of our lives. They change our lives and our life together. Get out the popcorn for this show, and immerse yourself in film scores and iconic movie moments — with David Greene on how “Star Wars” changed him, Ashley C. Ford on “The Nightmare Before Christmas,” Rubén Blades on the 1943 noir Western “The Ox-Bow Incident,” and more.
