From producer James Wan—one of the most influential figures in modern horror—and the Blumhouse/Atomic Monster team (creators of *Backrooms* and *Obsession*) comes a terrifying tale directed by Rob Savage. *Other Mommy* plunges into the dark world of a young girl named Bela, who forms a bond with a sinister entity that appears in her home—a creature bearing an uncanny resemblance to her mother.
