‘The Last House’ Shooting Locations: Where Was Netflix’s Latest Thriller Filmed

A gripping cast may be the reason you press play, but it is the slow-burning nightmare unfolding behind those locked doors that makes The Last House impossible to shake off.

Directed by Louis Leterrier, The Last House follows Jason and Ann Delgado after they discover their family home has become impossible to escape. Every door and window is mysteriously sealed, forcing them to raise their two children entirely within its walls as years pass and their reality grows increasingly disturbing. What begins as a desperate survival story slowly transforms into a surreal psychological nightmare unlike anything they could have imagined.

Premiering on Netflix on August 7, the film blends psychological horror with high-concept science fiction, following the Delgado family across a six-year timeline before revealing an astonishing twist that turns the house into something almost unrecognizable. With Wagner Moura fresh off The Secret Agent and Greta Lee leading the emotional charge, The Last House has already emerged as one of Netflix’s most talked-about genre releases of 2026 thanks to its ambitious storytelling, haunting visuals, and claustrophobic atmosphere.

With a talented ensemble anchored by powerful performances and a story that grows more unsettling with every twist, The Last House is far more than just another Netflix thriller.
