Elias and Lukas, Goodnight Mommy (2022)

Goodnight Mommy features double trouble—not just one creepy kid, but two. Elias and Lukas, active twin boys with well-groomed bowl cuts, are inseparable. But the fun summer days at their sprawling lakeside property are disrupted when their mother undergoes cosmetic facial surgery. She returns home with bandages around her face and odd behaviors that make the boys question her identity and convince themselves that they must torment her to make her confess who she really is.
What makes the twins so frightening how effortlessly they come up with the sadistic ways to inflict pain upon their mother. They tie her to the bed, Super Glue her lips shut, put cockroaches on her, and even set fire to the lavish family home. Goodnight Mommy delivers twice the evil to show how deep sibling bonds can run, often causing them to influence one another in the worst ways. A child’s boundless imagination can be used for bad ideas just as much as good.
