It’s Me, Margaret” filmmaking team she called her “family”: the writer-director Kelly Fremon Craig, left; Rachel McAdams; the producer James L. Brooks; and the film’s star, Abby Ryder Fortson, in Key West, Fla., March 26, 2023. Blume’s 1970 novel hits the big screen at a difficult political moment for a story with themes of bodily autonomy and religious choice. (Ysa Pérez/The New York Times)
