Louis Leterrier has called his new Netflix film The Last House the most difficult he has ever made — and it lands on the streaming service on 7 August 2026, one day after he said it. Speaking to The Hollywood Reporter, the French director opened up about a production that shifted formats midway through, moving from 35 mm film to digital as the shoot progressed. That kind of mid-flight format change is rare and expensive, a decision usually forced by circumstance rather than chosen for style.

The Last House is a sci-fi thriller starring Wagner Moura as Jason and Greta Lee as Ann, parents raising their two children inside a house that has been mysteriously sealed shut. The cast also includes Sid Edwards and Lewis Goody. Leterrier directs. The Hollywood Reporter categorises the film as a sci-fi thriller in its August preview coverage.

The film is also a milestone for Leterrier's new venture. He launched the production company Carrousel Studios with Omar Sy — his collaborator on the Netflix series Lupin, whose fourth season drops in October — and The Last House executive producer Thomas Brenski. Lupin, for readers unfamiliar, is one of Netflix's most-watched French-language originals, a modern heist mystery built around the gentleman-thief archetype created by Maurice Leblanc.

Leterrier is nothing if not busy. He was wrapping production on Liminal, a sci-fi action thriller for Apple, at the time of the interview. And he remains contracted to direct Fast Forever, the eleventh instalment in the Fast & Furious franchise — though he told The Hollywood Reporter he has not yet read a script. The biggest hurdle, he confirmed, is the budget.

The Fast franchise's commercial arithmetic explains why. The last three entries, including the spinoff Hobbs & Shaw, averaged roughly $730 million worldwide at the box office — healthy by most standards, but a decline from the series' peak years. China's attendance for Fast films has fallen between 45 and 65 percent, Leterrier noted, closing off the market that once inflated the franchise's international grosses. When a tentpole's budget climbs while its second-largest market shrinks, greenlights get harder to sign.

There is also a thread connecting Leterrier's Fast work to his earlier filmography. Daniela Melchior, who appeared in Fast X, said Vin Diesel told her he had discussed the future of her character with Leterrier during a flight from Rome to Mexico. That conversation dates to 2023, when Leterrier was deep in the franchise. Whether any of those plans carry into Fast Forever is not yet known — the script does not yet exist.

For now, Leterrier's focus is The Last House, a sealed-house mystery with two strong leads and a production story that, by his own account, tested him more than anything before it. Netflix subscribers can judge the result from 7 August.
