Hathaway's character is described as "a sort of Gaga–Taylor Swift hybrid." Michaela Coel plays a fashion designer who becomes entangled in Mother Mary's web. Coel, who went to techno clubs with Hathaway to prepare for her role, said that "it's very brave work that [Hathaway has] done."

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.
