Universal Pictures and Blumhouse released the official trailer for "Other Mommy," a psychological horror film starring Oscar-winning actress Jessica Chastain in a dual role. The thriller pits Chastain against herself as both a protective mother and her sinister doppelgänger, creating a high-stakes battle between the original and her malevolent clone.
Director Rob Savage helms the project, with producer James Wan bringing his horror expertise to the feature. The film adapts Josh Malerman's bestselling novel "Incidents Around the House," translating the author's psychological tension to screen.
