Stranger Things announces an extra episode on Netflix - but it's a making-of documentary, not a secret bonus finale

One Last Adventure: The Making of Stranger Things Season 5 will debut on Netflix January 12

After the much-hyped series finale on December 31, 2025, many fans suspected that Netflix wasn’t quite done just yet with Stranger Things — and they were right. Just not in the way in which they were expecting, as the streamer has announced the imminent release of a behind-the-scenes documentary for the show’s final season.

The one-off doc is titled One Last Adventure: The Making of Stranger Things 5, and comes from director Martina Radwan, whose work includes the acclaimed Girls State. Radwan released a statement to accompany the trailer for the movie. “I’m endlessly grateful to the Duffer Brothers for trusting me with a front-row seat to this incredible journey. Spending a full year on set with them was a true privilege — and an absolute thrill,” she said. “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 and document Seasons 1 through 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, always pushing the boundaries. The Duffers inspire everyone to be better, including myself, their process and the show represents everything I love about filmmaking.”

The Duffer Brothers released their own statement as well, adding, “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. 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.”

The trailer for the movie offers a glimpse of what fans can expect:

Sure, it’s not the ‘secret’ extra episode of the show itself some fans have been speculating about, but it’s definitely a welcome additional chance for them to say goodbye to their favorites.

One Last Adventure: The Making of Stranger Things 5 drops on Netflix January 12. Stranger Things is streaming now on Netflix.
