Greta Lee and Wagner Moura Star in ‘The Last House’: Netflix Sci-Fi Thriller Premieres This Year

Netflix has unveiled the trailer of its upcoming sci-fi thriller The Last House, a high-concept mystery starring Greta Lee and Oscar nominee Wagner Moura. Directed by Louis Leterrier, the film follows a family whose ordinary life turns into a nightmare when they discover they are mysteriously trapped inside their home with no way out.

Previously known under the working title 11817, the film premieres globally on Netflix on August 7, 2026.

A Nightmare With No Escape

The premise is simple but unsettling. One morning, a family of four wakes up to find that they can no longer leave their house. Doors won’t open, the outside world is unreachable, and an unseen force keeps them trapped.

As days turn into weeks, and weeks into years, the family must battle dwindling resources, emotional strain, and the psychological effects of prolonged isolation while searching for answers.

Netflix describes the film as a survival thriller centered on family, resilience, and the fear of the unknown.

Greta Lee and Wagner Moura Lead the Cast

Greta Lee stars as Ann, while Wagner Moura plays her husband Jason. Together, they anchor a story that relies heavily on emotional performances as the family struggles to maintain hope under impossible circumstances.

Lee broke through with her acclaimed performance in Past Lives and has since become one of Hollywood’s most sought-after dramatic actors. Moura, meanwhile, earned international recognition for Narcos before receiving widespread acclaim for The Secret Agent.

Speaking about the project, Moura said he was fascinated by the idea of waking up one day and finding himself permanently sealed inside his own home.

The supporting cast includes Riley Chung, Emma Ho, Noah Alexander Sosnowski, Gabriel Barbosa, Sam Lerner, and Audrey Anderson.

The Last House Trailer Out

The official trailer for The Last House dropped on June 15, 2026, and has already racked up over 18 million views in its first 48 hours. Clocking in at two minutes and fifteen seconds, the teaser opens with the mundane morning routine of a seemingly ordinary family before delivering the horrifying realization: every door, every window, every possible exit is inexplicably sealed shut by an invisible force. As days stretch into weeks, months, and then years, the trailer masterfully montages the psychological toll — children growing up knowing only four walls, parents aging under the weight of uncertainty, and the slow erosion of hope itself. 

The final shot — a brief, terrifying glimpse of something moving just beyond the rain-streaked windows — leaves viewers with a chilling sense of dread and sets up one of Netflix’s most anticipated thrillers of the summer.

Louis Leterrier Returns to Thriller Territory

Known for directing action-heavy projects such as The Transporter, Now You See Me, The Incredible Hulk, and Fast X, Louis Leterrier takes a more contained approach with The Last House.

Despite the limited setting, Leterrier has described the film as an intense survival story that transforms the concept of home into something frightening.

“The Last House challenges the idea of a safe haven,” the director said. “It’s about an ordinary family’s worst nightmare and the desperate fight to reclaim their freedom.”

The screenplay comes from Matthew Robinson, whose previous credits include Love and Monsters.

A Mystery Built Around Isolation

While the trailer reveals the family’s predicament, it deliberately avoids explaining what is actually trapping them.

Is the force supernatural? Technological? Government-made? Alien?

Netflix is keeping those answers hidden, allowing the mystery itself to become a major selling point.

The trailer shows the family initially believing the situation will pass quickly. Instead, the ordeal stretches on for years as they adapt to life inside their increasingly deteriorating home.

That long timeline separates The Last House from many other contained thrillers, allowing the film to explore how prolonged isolation affects both parents and children.

Comparisons to Other Psychological Thrillers

The concept has already drawn comparisons to films such as Vivarium, 10 Cloverfield Lane, and The Platform.

However, The Last House appears to focus less on horror and more on the emotional consequences of confinement.

Rather than simply asking how the family will escape, the film examines what happens to relationships when there is no clear end in sight.

Questions surrounding hope, trust, and survival appear to sit at the center of the story.

Why Netflix Has High Hopes

The film combines several ingredients that have worked well for Netflix in the past:

• A simple, instantly understandable premise
• Mystery-driven storytelling
• Recognizable stars
• A respected director
• Strong word-of-mouth potential

The streaming giant has found success with high-concept thrillers that encourage audience discussion, and The Last House appears positioned to follow that model.

The mystery surrounding the family’s imprisonment is likely to generate speculation online once viewers begin watching.

A Potential Summer Breakout

The combination of Greta Lee’s rising profile, Wagner Moura’s critical acclaim, and Leterrier’s experience handling suspense makes The Last House one of Netflix’s most intriguing original films of the summer.

Its premise taps into a universal fear: being trapped in a place that should feel safe.

By turning a family home into a prison, the film transforms an everyday setting into something deeply unsettling.

Whether the answers behind the mystery prove satisfying remains to be seen, but the concept alone has already generated significant interest ahead of release.

Release Date

The Last House premieres exclusively on Netflix worldwide on August 7, 2026.
