The world of Stranger Things isn’t disappearing just yet.
Per Forbes, while the Netflix juggernaut wrapped its nine-year run with a final episode on December 31, fans are getting one more deep dive into Hawkins with a new behind-the-scenes documentary titled One Last Adventure: The Making of Stranger Things 5.
The documentary arrives on Netflix on January 12 at 3 a.m. ET and offers an inside look at how the show’s final season came together—on and off the screen. Directed by Martina Radwan, the two-hour project follows the cast, creators, and crew throughout production, capturing everything from writers’ room debates to the emotional final days on set.
Netflix describes the film as “a sweeping behind-the-scenes chronicle” of the show’s final season, highlighting how Stranger Things evolved from a nostalgic sci-fi experiment into a pop-culture phenomenon.
The documentary features interviews with creators Matt and Ross Duffer, along with extensive footage of the ensemble cast reflecting on the end of a series that defined much of their lives.
One moment that stands out centers on a creative decision fans immediately noticed: the absence of Demogorgons during the show’s final battle. In the documentary, Matt Duffer explains that the finale introduced “the giant monster—that’s what’s new,” while writer and co-executive producer Kate Trefry raises concerns about potential “Demo fatigue.” Ross Duffer ultimately agrees, noting that revisiting too many familiar elements could feel exhausting.
Radwan told Variety that the documentary intentionally leaves those creative conversations open-ended. “You see them thinking in real time,” she said, explaining that disagreements were part of the process. “They disagree, and they resolve it later.”
Beyond creative choices, One Last Adventure leans heavily into the emotional weight of saying goodbye. Radwan described filming the final wrap as especially difficult, noting that for many involved, the show represented “half their life.” She added that it was important the documentary felt like “one goodbye,” rather than separate farewells.
