I just watched the trailer for One Last Adventure: The Making of Stranger Things 5, and I’ll be honest—I got a little emotional. After nearly a decade of following this show, seeing the cast and crew say their goodbyes hit differently than I expected.
Netflix just released the official trailer for what they’re calling a “never-before-seen behind-the-scenes documentary” chronicling the making of Stranger Things‘ fifth and final season. If you’ve been with this show since 2016 like I have, prepare yourself.
What the Trailer Reveals
The newly released trailer gives us our first real look at what One Last Adventure will cover. Here’s what stood out to me after watching it several times (yes, several):
Key Moments from the Trailer:
- Emotional cast interviews as they film their final scenes
- The Duffer Brothers discussing the pressure of ending the series
- Behind-the-scenes footage from Season 5’s production
- Glimpses of the cast—now adults—reflecting on growing up in Hawkins
- What appears to be the final day of filming (bring tissues)
The documentary’s tagline says it all: “One last time.” Netflix is positioning this as the definitive sendoff for one of their most successful original series.
Why This Documentary Matters
Having covered Netflix content for years, I’ve seen my share of promotional “making of” specials. But One Last Adventure appears to be something more substantial—a genuine documentary about closing a cultural phenomenon.
Stranger Things isn’t just another TV show. When it premiered in July 2016, it launched Millie Bobby Brown’s career, revitalized Winona Ryder’s, and reminded a generation why we fell in love with 1980s Spielberg in the first place. This documentary chronicles the end of that era.
What makes this significant:
- The cast literally grew up making this show—they started as kids and are finishing as young adults
- Production spanned nearly a decade, surviving pandemic shutdowns and industry strikes
- This is Netflix’s first true cultural phenomenon getting a proper documentary farewell
- The show’s influence extended far beyond streaming, impacting fashion, music (hello, Kate Bush revival), and pop culture
What We Know About the Documentary
Based on the trailer and Netflix’s official announcement:
Title: One Last Adventure: The Making of Stranger Things 5
Tagline: “One last time. Watch the never-before-seen behind-the-scenes documentary on the making of Stranger Things 5.”
Format: Feature-length documentary
Focus: Behind-the-scenes production of the final season
Release Date: Not yet announced (though likely timed with Season 5)
My Reaction to the Trailer
As someone who’s been covering this show since the beginning, what struck me most wasn’t the production footage or special effects breakdowns—it was the genuine emotion on display.
There’s a moment in the trailer where you can see the weight of saying goodbye hitting the cast. These aren’t actors pretending to be sad for the camera. These are people who spent their formative years together, built lifelong friendships, and created something that became bigger than any of them imagined.
Finn Wolfhard, Millie Bobby Brown, Gaten Matarazzo, Caleb McLaughlin, Noah Schnapp, and Sadie Sink were kids when this started. They’re adults now. That transition, captured in real-time over five seasons, is rare in television history.
What to Expect from the Full Documentary
Based on the trailer and similar Netflix documentaries, here’s what I anticipate we’ll see:
Likely Content:
- Cast Retrospectives: Deep interviews with the core cast reflecting on their journey
- Duffer Brothers’ Vision: How Matt and Ross Duffer planned the ending from the beginning
- Production Challenges: The reality of filming the most ambitious season yet
- Emotional Goodbyes: Final day footage and wrap party moments
- Legacy Discussion: What Stranger Things meant to everyone involved
- VFX Breakdowns: How they brought the Upside Down to life one last time
What Sets This Apart: Unlike typical promotional content, this appears to have real access. Netflix gave the documentary team the kind of behind-the-scenes access that captures genuine moments, not just polished soundbites.
Season 5: Where Things Stand
For those keeping track, here’s the current status of Stranger Things Season 5:
- Production Status: Currently filming, expected to wrap in 2026
- Episode Count: Eight episodes confirmed by the Duffer Brothers
- Timeline: Set partially in fall 1987, picking up after Season 4’s cliffhanger
- Expected Release: Late 2026 (unconfirmed, but Netflix’s typical pattern suggests this)
- What We Know: Plot details remain tightly guarded, though the Duffers have promised this season will answer every remaining question
The documentary will likely release either just before Season 5 (as hype-building) or immediately after (as a victory lap). My money’s on a simultaneous or near-simultaneous release.
The Cultural Impact Context
To understand why this documentary matters, you need to understand what Stranger Things accomplished:
By the Numbers:
- Launched in 2016 with relatively unknown child actors
- Became Netflix’s most-watched English-language series (until Wednesday)
- Made Kate Bush’s “Running Up That Hill” a #1 hit 37 years after its release
- Generated billions in merchandise revenue
- Influenced everything from Halloween costumes to fashion trends to video games
Beyond Statistics: I remember when Season 1 dropped and nobody was talking about it. Then suddenly everyone was talking about it. It was the first Netflix show that felt like true appointment television, even though you could watch it whenever you wanted. That’s cultural penetration.
What Fans Are Saying
The trailer dropped just hours ago, and the Stranger Things fandom is already in its feelings. Social media reactions I’ve seen range from excited to devastated—often in the same post.
Common Themes:
- Nostalgia for how the show defined their teenage/young adult years
- Appreciation for watching the cast grow up
- Anxiety about how the story will end
- Gratitude for the Duffer Brothers’ commitment to a planned ending
One comment I saw perfectly captured the mood: “I’m not ready to say goodbye, but I’m glad they’re saying goodbye right.” That sums it up.
Why Netflix Is Doing This Right
As someone who analyzes streaming strategy, Netflix’s approach here is smart for several reasons:
- They’re treating their flagship show with respect rather than just milking it for content
- The documentary serves multiple purposes: marketing for Season 5, fan service, and historical record
- They’re learning from past mistakes: Remember how Game of Thrones ended with minimal fanfare? This is the opposite approach
- It extends the franchise value without diluting the core story with unnecessary spinoffs
This is how you end a cultural phenomenon. Not with a whimper, but with a proper celebration.

What We’re Still Waiting to Learn
Netflix’s trailer answers some questions but leaves plenty unresolved:
Unanswered Questions:
- Exact Release Date: When will the documentary premiere?
- Runtime: Is this a 90-minute feature or a multi-hour series?
- Director/Producer: Who’s actually making this documentary?
- Scope: Does it cover just Season 5 or the entire series journey?
- Exclusive Content: Will there be deleted scenes or alternate endings discussed?
I expect Netflix will announce more details soon, possibly during their “What Next” event on January 7th.
My Take: Why I’m Actually Excited
I’ll admit I’m typically skeptical of “making of” content. Too often, it’s just glorified marketing that tells you nothing substantive. But this trailer suggests something different.
What excites me isn’t the production secrets or the VFX breakdowns—though those will be cool. It’s the human story. Watching these kids become adults while making a show that defined a generation of streaming content is genuinely compelling television.
The best documentaries don’t just show you how something was made. They show you why it mattered to the people making it. If One Last Adventure captures even a fraction of that emotional journey, it’ll be worth watching even for non-fans.
The Bigger Picture
Stranger Things proved that streaming could create true cultural moments in an era of fragmented attention. It showed that nostalgia, done right, isn’t pandering—it’s a legitimate storytelling tool. And it demonstrated that you could plan an ending and stick to it, rather than dragging a show out until it dies.
This documentary is more than a sendoff. It’s a case study in how to do television right in the streaming era. Film students will be watching this years from now.
