Netflix has announced a new documentary following the making of the final season of Stranger Things. Titled One Last Adventure: The Making of Stranger Things 5, the film will premiere on Netflix on January 12, 2026.
Directed by Martina Radwan, the documentary will provide “an inside look at the years of effort and craft that went into the final installment of the Duffer Brothers’ generation-defining series.” Radwan told Netflix’s Tudum, “I’m endlessly grateful to the Duffer Brothers for trusting me with a front-row seat to this incredible journey.”
She continued, “Spending a full year on set with them was a true privilege — and an absolute thrill. Being able to get close and watching them bring this beloved show to life in real time was pure joy. I only wish I could travel back in time and document Seasons 1-4. From the cast to their long-time collaborators, everyone welcomed me with remarkable generosity, openly sharing their personal and collective experiences from a decade of creative filmmaking. The Duffers always push boundaries and inspire everyone to be better, including myself. Their process and the show represent everything I love about filmmaking.”
The new trailer highlights key moments from the fifth season, including emotional footage of Matt and Ross Duffer, the show’s creators, addressing the cast and crew.
Reflecting on their journey, the Duffer Brothers said, “Growing up in Durham, North Carolina, we dreamed of becoming filmmakers — but Hollywood felt impossibly far away. Everything changed when we watched the behind-the-scenes documentaries for The Lord of the Rings — on-the-ground films that showed the real nuts and bolts of how a massive production actually gets made.”
“We saw how stressed Peter Jackson was and thought: yep, that’s the dream. With the decline of physical media, that kind of behind-the-scenes storytelling has largely disappeared,” the Duffer Brothers said. “We wanted to bring it back. One Last Adventure: The Making of Stranger Things Season 5 — beautifully captured and directed by Martina Radwan — is our attempt to do just that. If you love Stranger Things, or if you’re simply curious how a major Hollywood production comes to life, this one’s for you.”
In Stranger Things 5, the gang gears up to track down and ultimately defeat Vecna, bringing an end to the long-standing nightmare. For one final time, the entire group comes together. The show debuted in 2016, becoming one of Netflix’s most popular series.
The streamer also released a new trailer offering a behind-the-scenes look at the series’ concluding chapter.
