David Harbour (DTF St. Louis) and Gaby Hoffmann (Springsteen: Deliver Me from Nowhere) have inked deals to star in Little One, a dark comedy marking the feature directorial debut of Alex Kavutskiy, which reunites the Weapons duo of Zach Cregger and Roy Lee.

Character details are under wraps. Shooting in Los Angeles under a California tax credit this month, Little One watches as a sudden change in a child’s behavior threatens to tear a picture-perfect family apart. Alex Lebovici’s Hammerstone Studios is financing the project, in a reunion with Cregger and Lee post-Barbarian, with Lebovici also to serve as exec producer.

Written by Kavutskiy, the film’s other producers include Chris McEwen (Love, Simon), along with Amanda Phillips and Melina Torres of Soto Productions (Winner, The Assistant). Ibrahim Mohammed of Script 2 Screen will exec produce and co-finance the film alongside Chase Vergari. Kevin G. Lee will exec produce for Astria Studios, which is providing additional financing, with First Take Media Capital and David Goldman also aboard as EPs, along with Michael Learner, Karina Manashil and Sian McArthur under Hammerstone. Sacker Entertainment Law is handling production legal.

Recently seen starring opposite Jason Bateman and Linda Cardellini in another dark comedy, the lauded HBO series DTF St. Louis, Harbour just last night earned a Gotham TV Award for his supporting role. The series, created by Steven Conrad, led the night with two wins, also prevailing in Outstanding Limited or Anthology Series.

Harbour earlier this year lent his voice to Sony’s hit animated feature Goat, which grossed over $194 million worldwide, prior to that wrapping up his five seasons with Stranger Things. He has a stacked slate of projects up ahead, and will have a busy December in particular, with the release of both Universal’s Violent Night 2 and Disney/Marvel’s Avengers: Doomsday, where he reprises his role of Alexei Shostakov aka Red Guardian. Other upcoming projects include Lionsgate’s John Rambo opposite Noah Centineo, Courteney Cox’s crime thriller Evil Genius, and the horror thriller A Head Full of Ghosts from the duo of Severin Fiala and Veronika Franz. Harbour is repped by WME and Sloane, Offer, Weber & Dern.

Known for projects like Transparent and C’mon C’mon, Hoffmann is coming off turns in Netflix’s thriller series Eric, opposite Benedict Cumberbatch, and 20th’s Springsteen biopic Deliver Me from Nowhere, opposite Jeremy Allen White. Next up, she’ll be seen in both A24’s Deep Cuts from Sean Durkin and Scott Cooper’s Netflix thriller Time Out starring Adam Sandler. She is repped by Gersh, OPE Partners, and Peikoff Mahan.
