In Conversation with the Duffer Brothers: Inside “Stranger Things 5”, Vecna’s Endgame, and the Three-Volume Finale

Stranger Things became a cultural phenomenon and must-watch television by blending ’80s nostalgia, character-driven storytelling, and high‑concept sci‑fi horror into an emotionally accessible series. There really is something in the show for everyone. Its memorable imagery — the Upside Down, Eleven’s powers, and villains like Vecna.

To summarize, Season 1 (2016) introduces Hawkins, the disappearance of Will Byers (Noah Schnapp), and Eleven (Millie Bobby Brown), establishing the Upside Down. Season 2 (2017) expands the mythology with new characters and the looming Mind Flayer threat as the kids face growing personal and supernatural challenges. Season 3 (2019) ramps up the spectacle with larger set pieces, Cold War elements, and relationship payoffs. Season 4 (2022) goes global and darker, revealing Vecna and deepening the lore scope of the series. Season 5 (2025) concludes the saga in three volumes — two multi-episode drops and a final event episode — delivering a cinematic, memorable finale. Stranger Things pays homage to various influences and references that gave birth to and sustained this immensely popular series. There is almost a meta quality to the show because it’s self-referential and brings the conclusion a full circle to its first season.

The Duffer Brothers Matt and Ross, offer their thoughts on Stranger Things and what they learned about filmmaking over almost a decade.

“We started out talking about a style of storytelling that we weren’t seeing much anymore, that we grew up loving. And especially, we hadn’t seen it much on television. What does this type of storytelling look like in a long format? This was kind of a new thing all the way back in 2015 in terms of being able to tell a story more movie-like with shorter seasons,” Matt says.

The whole process was very organic as the series evolved over five seasons. The Duffer Brothers initially envisaged themselves working in movies, but Netflix had other plans. Stranger Things is the best of both worlds influenced my the highly talented cast.

“The show becomes its own thing. And so, this season, felt less and less like we’re relying on, or looking back at the films that inspired us. And it’s more in conversation with the show.”

Stranger Things 5 was an opportunity for the Duffers to finalize the themes and watching the child cast grow up over the course of the show. “And especially the final episode, is kind of a commentary on what it felt like making the show and saying goodbye.”

On Both Writing and Directing The Series

The Duffer Brothers reflect on their humble beginnings as independent filmmakers as the scale of each episode became larger and more cinematic. Prior to Stranger Things, they only directed one small movie called Hidden and written a few episodes of television.

“We were used to collaborating with one another and not with a large group of people. I think part of it was us becoming more comfortable with doing a deep dive on people and allowing them into our process and sharing our process with them. You become this big hive mind.”

As the scale of the show increased, so did the challenges – which Matt and Ross embraced. They quote an example of a “one-er” (one take) battle sequence is Stranger Things 5 with enormous choreography, action and visual effects.

“When you’re writing it, you don’t have to think about how painful it is going to be to execute some of this stuff. And when you’re starting to get to the point of prepping something, you’re asking, ‘What were we thinking?’ Because this is kind of a nightmare. It’s a big action sequence. It’s at night. It involves an insane amount of stunts. And it has children in it.” Maintaining their focus on the children more than the monsters allowed them to stay grounded during the process.

Growing Up With The Cast

Finn Wolhard, who plays Mike Wheeler, has been on the series since the beginning. The Duffers recount the emotional relationship they built with Finn and some of the more seasoned child actors over the years as they matured. Matt and Ross allowed Mike to lead some scenes because of his intimate knowledge of the show. Finn mentored the newcomers to the series like Sadie Sink, who plays Max Mayfield and Nell Fisher who portrays Holly Wheeler. Similarly, Noah Schnapp, who plays the missing Will Byer, directed the younger actors.

As Stranger Things 5 moves into Volume 2, more questions are raised about Max in the grander scheme of things and her character growth. where he leads an army of Demogorgons in a battle against the residents of Hawkins.

“We always knew that Max was in Vecna’s mind in the Season four, but I think it was in the breaking of Season five, we didn’t realize that she was going to intersect with Holly. And that’s when everything really started to click. We didn’t know until we put Joe Keery (Steve Harrington) with Gaten Matarazzo (Dustin Henderson) that Steve and Dustin would be great.”

Vecna’s Mindscape

“This is one of the weirdest, most left field storylines in that we’re dealing with memories. I think what’s been part of the fun of this show is that in each season, we’re able to add new ideas to the mythology. And stuff that we dipped our toe in in the first couple seasons, we’re now able to go all the way in.”

“I think ultimately what we realized is we wanted to continue to ground it in the memories. It can be as simple as something like 1950s high school hallway. And the juxtaposition of that with this cave is automatically going to create a level of mystery that we don’t need to push it further than that.”

“We talked a lot about The Cell and the Tarzan movie. There are a few movies and shows that do play around with memories. And in that case, it’s very specific because you’re in the memories of a bad person, of a serial killer. So we looked at stuff like that in terms of how best to pull off Vecna’s mind. We talked about Picnic at Hanging Rock and that sense of you having this feeling that something is off.”

Fusing Big Spectacle with Character Reveals

“We want to scale up with bigger visual effects and set pieces, but we don’t want to lose sight of the characters or the emotion. I think that’s the most important thing. We love these kind of sequences in other movies and shows, but sometimes we do find ourselves zoning out because we’re not connected to what’s happening on an emotional level.”

“You can have the most incredible action sequence ever, but if I’m not invested in the people on the ground, then I really do fall asleep sometimes. I think the key for us and the sweet spot for us is if it is the action is sort of climaxing at the same time as something in a character arc or something, there’s an emotional climax.”

“I think we were most successful in Season four with a Dear Billy episode where we had Max’s emotional journey climaxing at the same time as this incredible, peak visual effects, spectacle moment. We had Will’s emotional journey, which we’d been building from episode one through four, climaxing at the same time as we had this visual effects kind of extravaganza. So when you’re building to this moment with Will, then you devise the set piece around that to enhance it rather than wedge in the character.”
