In Speak No Evil, an American family accepts an invite to spend the weekend at the idyllic country estate of a charming British family they befriended on vacation. But what begins as a dream holiday soon warps into a snarled psychological nightmare. 

The upcoming horror film stars James McAvoy as the charismatic estate owner whose hospitality masks a deep and unspeakable darkness. In a new promo clip for the film, McAvoy and his co-stars tease what’s to come for fans.

“Speak No Evil is about social and psychological darkness… you feel like you’re trapped in a cage the whole time,” teases McAvoy.

His co-star Mackenzie Davis has some more straightforward advice.

“Never hang out with vacation friends after the vacation,” she says.

Check out more cast perspectives on the film in the new clip below.

Speak No Evil comes from Blumhouse, as an American adaptation of a 2022 Danish horror flick Gæsterne. The original Danish feature landed an impressive 11 Danish Film Award nominations, the country’s equivalent of Academy Awards.

This iteration comes from writer/director James Watkins (The Woman in Black).

The film stars Davis (Terminator: Dark Fate) and SAG award-winner Scoot McNairy (A Quiet Place Part II) as the American couple Louise and Ben Dalton, who, along with their 11-year-old daughter Agnes (Alix West Lefler, Riverdale), accept the weekend-holiday invitation of Paddy (McAvoy), his wife Ciara (Aisling Franciosi, Game of Thrones) and their furtive, mute son Ant (newcomer Dan Hough).

Speak No Evil premieres in theaters September 13.
