When Odysseus and his troops meet up with the minor goddess Circe in Christopher Nolan’s The Odyssey, things get pretty scary. But that fear may have been undercut because most audiences who saw the film this weekend were probably still recovering from a trailer Universal debuted exclusively in front of the film. It’s called Other Mommy, it stars Jessica Chastain, and, to be frank, it’s freaking terrifying. Directed by Rob Savage and based on the New York Times bestselling novel Incidents Around the House by Josh Malerman, Other Mommy has the simplest, scariest premise imaginable. What if your mother wasn’t your mother? What if a monster could look like your mother? Check out the trailer that scared Christopher Nolan fans all weekend, which is now online after playing only in theaters this past weekend. Now, as we said, that trailer is incredibly effective. Not just from its slow burn leading into all those crazy fast cuts, but the way it puts you in the shoes of the young girl. The terror that comes from not being able to trust the most important person in your life is palpable. How that person would react to being impersonated is almost equally mind-boggling. And instantly you simply need to know what this horror is, why it’s targeting this family, and what they’re going to do to stop it. One ticket for Other Mommy, please.
