Following the announcement that David Harbour (DTF St. Louis) and Gaby Hoffman (Springsteen: Deliver Me from Nowhere) have joined the upcoming dark comedy Little One, from Weapons producers Zach Cregger and Roy Lee, the film star cast has expanded with actors Amy Smart (Stargirl), Chiara Aurelia (Cruel Summer), Derek Luh (Gen V) and Redding Munsell (At the Sea).

Smart, last seen in the 2024's Rally Caps, has starred in Starship Troopers (1997), The Butterfly Effect (2004), and Crank films (2006, 2009).

Munsell and Aurelia play the children who are the core of the film, whose parents will be played by Harbour and Hoffman. Helmed and penned by debutant Alex Kavutskiy, Little One, which curiously follows the theme of Weapons, revolves around a sudden change in a child's behaviour that endangers a picture-perfect family.

Kavutskiy worked as a writer in the recently released Jury Duty Presents: Company Retreat. His previous directing credits include the Sundance short Squirrel. He has also co-authored an upcoming book, The Tribe and I Have Spoken.

Little One marks the duo's fourth collaboration after Barbarian (2022), Weapons (2025), and Resident Evil, which is slated for release this September. As producers, Little One is their sophomore production.
