Goodnight Mommy (2015) is an unsettling horror film built on scars (physical and psychological) that upset the connection between a mother (Susanne Wuest) and her sons, adolescent twins named Lukas and Elias played by real-life twin brothers Lukas Schwarz and Elias Schwarz. That fraternal connection is apparent in every scene, not just affection but the easy physical and emotional relationship between them, a sharp contrast to the void between them and their mother, who returns home from the hospital with her head covered in bandages from unspecified surgery.
Mom returns a changed woman, or so we gather from the brothers, who find her cold, aloof, demanding in a way she never was before. She locks them in their room like a fairytale wicked stepmother and even refuses to make dinner for Lukas, the quiet one who drives the suspicion that this woman is an imposter. Yet every time the suspicion tips to conspiracy or possession, filmmakers Severin Fiala and Veronika Franz tilt the scales in the other direction, offering a glimpse into mom’s troubles. She’s recently separated from her husband and this hospitalization (what is it? Cosmetic surgery, or something more serious?) only adds to her trauma, while the boys get lost deeper into their own private world.
There’s an element of unreality to the situation—why have the boys been left alone while mom was in the hospital, and if she needs such isolation and rest for recovery, why no nurse for her or nanny to watch over the kids, or at least a friend to drop over for comfort or a helping hand—but that isolation is also essential to the anxious atmosphere. Apart from a delivery man with a cache of frozen food and a couple of shuffling Red Cross volunteers seeking donations, they are cut off from the outside world and the filmmakers make the house increasingly alien and eerie. The psychological turns physical, all the more terrifying because it is so direct and intimate, a chamber drama of suspicion and desperation built on fear. Where is mama indeed.
