On January 12, 2026 at 9:00 a.m. (France time), Netflix is releasing an original behind-the-scenes documentary dedicated to the final chapter of Stranger Things. Titled La dernière aventure: Le making-of de Stranger Things 5, this film drops alongside the fifth and last season and looks back on ten years of production, teamwork, and creative evolution around the series created by Matt and Ross Duffer.
A close-up look at Stranger Things’ final months
Directed by Martina Radwan, the documentary spends nearly a full year following the Stranger Things crew during the shooting of season 5. With the camera staying close to the action, it captures the key stages of this final chapter: rehearsals, work on set, and the day-to-day efforts of technicians, actors, and creators as they bring the conclusion to life.
Presented by Netflix as an insider’s look at the years of work needed to land the series ending, the film explores how a production that has become a global phenomenon operates on a daily basis. Beyond the logistics, it also foregrounds the human side of this collective journey, following people who are closing out a project that has profoundly shaped their careers and personal trajectories.
How Martina Radwan and the Duffer brothers approach the story
Within the documentary, Martina Radwan describes the project as a rare opportunity, made possible by the trust Matt and Ross Duffer placed in her. She highlights how generous the teams were in opening up about their memories, doubts, and working methods after a full decade of continuous creation.
For their part, Matt and Ross Duffer explain that they wanted to reconnect with the tradition of in-depth production documentaries, which have become less common with the decline of physical media. Drawing inspiration from the behind-the-scenes films made for The Lord of the Rings, they aim to show in concrete terms how a series of this scale is put together, stepping away from purely promotional footage.
- Long-term immersion on the sets of season 5
- Direct conversations with the creators, cast, and long-time collaborators
- A clear-eyed look at the end of a major creative cycle
Why this documentary matters for understanding Stranger Things
Produced by Angus Wall, Terry Leonard, and Kent Kubena for MakeMake Productions, La dernière aventure is designed as a way to pass on knowledge. It sheds light on the artistic and organizational decisions that shaped Stranger Things, a series that has become a key part of contemporary pop culture since its launch.
While season 5 is set in the fall of 1987 and brings the fight against Vecna to a close, the making-of serves as a more intimate counterpart to the fictional story. It speaks both to long-time fans and to anyone curious about what it really takes to pull off a production of this scale. It’s an invitation to see what happens behind the curtain before the page is turned for good.
La dernière aventure: Le making-of de Stranger Things 5 will be available exclusively on Netflix starting January 12.
