H2: Release date and where to watch
The Stranger Things documentary One Last Adventure: The Making of Stranger Things 5 arrives on Netflix on Jan. 12, 2026. The feature-length behind-the-scenes film will stream exclusively on Netflix and goes deep into the years of work behind the show’s final season.
H2: What the documentary covers
One Last Adventure chronicles the making of Season 5 with a focus on the people who built it — the cast, the Duffer Brothers, long-time collaborators and the crew. The film captures pivotal moments on set, editorial meetings, practical effects work and the emotional goodbyes as the team wraps a decade-defining series.
The new trailer teases tearful addresses from Matt and Ross Duffer to cast and crew, key on-set sequences, and candid interviews revealing how the series came to its final chapter. For fans and film lovers alike, the documentary aims to show the mechanics behind large-scale storytelling and the emotional cost of saying goodbye to an epic production.
H2: Director and creative approach
Martina Radwan (Girls State) directed the documentary. Radwan spent a full year on set, saying she felt “endlessly grateful” to be given a front-row seat to the production. She highlights the generosity of the cast and crew and the Duffers’ drive to push creative boundaries.
The Duffer Brothers told Tudum they were inspired by classic behind-the-scenes documentaries—like The Lord of the Rings featurettes—that revealed the “nuts and bolts” of filmmaking. With the decline of physical media, they wanted to restore that form of behind-the-scenes storytelling, delivering an on-the-ground chronicle of how a major TV production is made.
H3: Who appears in the film
Expect core cast members — including Millie Bobby Brown, Finn Wolfhard, Sadie Sink and others — along with production heads and collaborators who helped shape the final season. The documentary appears designed both as a making-of primer and a farewell to the series’ decade-long run.
