Other Mommy
by Hope Madden
A great deal goes unspoken in Other Mommy, a horror film informed by the complex idea that it’s what breaks your heart that makes you human.
Jessica Chastain is Aurora Martin, mommy to 7-year-old Bela (Arabella Olivia Clark). Chastain is also Other Mommy, a mommy-shaped entity who wants Bela’s permission to become human.
If a lot of this sounds familiar—a child, unhappiness in the house, an imaginary friend who’s less imaginary than demonic—credit director Rob Savage and writers Nathan Elston and Josh Malerman for complicating the tale with fairly realistic (if unreasonably wealthy) human damage.
And, of course, Chastain for being game for some serious freakiness.
Jay Duplass keeps things grounded in tenderness as Daddo, the one reminder that humans can be wonderful. A strong supporting cast includes Karen Allen, Sean Kaufman, and Arian Moayed, but Savage’s investment in Clark to keep us engrossed pays off.
She reminds you of a very young Mckenna Grace. Her soulful attention and authentic performance create real tension. The youngster carries a lot of this film and manages beautifully.
Other Mommy spins a cautionary tale about tricksters, letting the wrong person into your heart, people who aren’t as they seem, and the generational damage done by less-than-ideal parents.
Like a lot of imaginary friend horror films, Other Mommy writes itself into a bind it can’t entirely escape. But the cast mines the script for a backstory they wear in their gestures and behaviors, and Savage throws enough random insanity at you that things never feel predictable.
It’s not an uncontested win, but Other Mommy delivers creepiness that picks a particular scab.
