Anne Hathaway opened up in a new Vogue cover story about the making of “Mother Mary,” the upcoming A24 music drama from director David Lowery. Co-starring Michaela Coel, the film stars Hathaway as a pop diva who flees her tour during an existential crisis and seeks out the old friend who helped craft her public

The Oscar winner offers details about the film, which delivered the most challenging role of Hathaway’s career during a shoot in Germany where people may have gone “temporarily, mildly insane.”

Mother Mary stars internet faves Anne Hathaway and Michaela Coel, is directed by Ghost Story and The Green Knight ’s David Lowery, and is soundtracked with original music by Jack Antonoff and Charli XCX.
