When an American family is invited to spend the weekend at the idyllic country estate of a charming British family they befriended on vacation, what begins as a dream holiday soon warps into a snarled psychological nightmare. From Blumhouse, the producer of The Black Phone, Get Out and The Invisible Man, comes an intense suspense thriller for our modern age, starring BAFTA award-winner James McAvoy (Split, Glass) in a riveting performance as the charismatic, alpha-male estate owner whose untrammeled hospitality masks an unspeakable darkness. Speak No Evil stars Mackenzie Davis (Terminator: Dark Fate, Halt and Catch Fire) and SAG award-winner Scoot McNairy (Argo, A Quiet Place Part II) as American couple Louise and Ben Dalton, who, along with their 11-year-old daughter Agnes (Alix West Lefler; The Good Nurse, Riverdale), accept the weekend-holiday invitation of Paddy (McAvoy), his wife Ciara (Aisling Franciosi; Game of Thrones, The Fall) and their furtive, mute son Ant (newcomer Dan Hough). Written for the screen and directed by James Watkins, the writer-director of Eden Lake and the award-winning gothic ghost story The Woman in Black, Speak No Evil is based on the screenplay of the 2022 Danish horror sensation Gæsterne, written by Christian Tafdrup and Mads Tafdrup.
