In an interview with Vogue magazine a little more than a year ago, the director Sofia Coppola mentions that taking on “Priscilla,” her new movie based on Priscilla Presley’s 1985 book “Elvis and Me,” was done as a “pivot” away from an Edith Wharton adaptation that was proving burdensome. Wanting to make “one film with one idea,” Ms. Coppola likened Ms. Presley’s experience as a teenager coming of age within the “amplified world” of Elvis Presley as “kinda similar to Marie Antionette.”
