Julia, an accomplished music conductor, and her husband haven’t been able to have a child on their own, so they turn to an unlikely source: an experimental new fertility clinic run by a charming doctor. After a successful procedure, the couple finally has the child they’ve long wanted, but the fertility’s bizarre practices turn their lives into a nightmare, one marked by a horrifying question: Is the child really theirs? A dark and at times darkly funny look at the most extreme of parental anxieties, Austrian writer-director Johanna Moder’s MOTHER’S BABY is an excellent and wonderfully acted entry into the ROSEMARY’S-BABY-inspired “maternal horror” canon. —Matt Barone
