A24’s Undertone Sets Prequel as UK Release Draws Fresh Reviews

The low-cost, sound-first horror turned box-office surprise is now being built into a planned trilogy.

Overview

  • Ian Tuason confirmed the next film as a prequel centered on Mike and Jessa and said talks with A24 about a third entry are underway.
  • Undertone expanded to UK cinemas with new notices that range from 2-star reviews by British outlets to enthusiastic fan reactions on social media.
  • The microbudget feature, made for about $500,000, opened to roughly $9.3 million and went on to top $18 million in the U.S.
  • The film leans on immersive sound over on-screen scares, using a single location and mostly voice-only performances to let audiences imagine the horror.
  • Abyzou, a demon from ancient folklore tied to attacks on children, frames the movie’s focus on pregnancy and motherhood within religious imagery.
