A Pope John Paul II lollipop. An Elvis Presley shower curtain. A Princess Diana teacup. These are just some of the countless pieces of memorabilia that these pop culture icons' most devoted fans collect and cherish - but why? The Faithful's director, Annie Berman, explores the deep veneration and legacies of the Pope, the Princess, and the King. Over the course of 20 years, Berman profiles these figures' biggest fans and makes numerous pilgrimages to Vatican City, Graceland, and Kensington Palace. As the years go by, the film itself becomes increasingly entwined with Berman's daily life and identity, much like how the officially licensed knick-knacks define the fans she filmed.
