The official trailer for *Verity*, adapted from Colleen Hoover’s 2018 bestseller, presents the film as a dark psychological thriller that leans into the novel’s disturbing and horror-inflected material. Dakota Johnson plays struggling writer Lowen Ashleigh, hired to complete paralysed author Verity Crawford’s work, before discovering a troubling manuscript at the Crawford home that makes her question Verity, her husband Jeremy, and her own reality.

Anne Hathaway plays Verity, alongside Josh Hartnett as Jeremy, and the trailer suggests the film may show Verity more directly through flashbacks and dialogue than the book does. This could alter how viewers interpret the story’s famously ambiguous ending, while the R-rated adaptation includes recognisable unsettling moments such as a canoe incident and jump scare; it is Hoover’s fourth book-to-screen project and her first R-rated adaptation.
