The makers of Stranger Things have shared a surprising behind-the-scenes truth. The final episode of this Sci-Fi show started filming before the script was fully finished.
This detail was revealed in the documentary One Last Adventure: The Making of Stranger Things 5. In the film, creators Matt Duffer and Ross Duffer speak honestly about the pressure they faced while making Season 5.
Matt Duffer explained that the team did know the ending of the story. Everything was planned. But the problem was time. The writing of the last episode was still happening while cameras were already rolling.
The final episode is titled “The Rightside Up.” It will show the last battle against Vecna, the show’s main villain. During filming, even some crew members were unsure what would happen next. A production assistant shared that they were shooting Episode 8, even though it was not completely written.
Matt Duffer admitted this was a very strange experience. He said he had never filmed an episode like this before and did not enjoy jumping straight to the final chapter. Still, filming had to move forward.
The pressure did not only come from time. Matt said the team was also feeling stress from production schedules and Netflix expectations. There was a lot of noise and urgency around finishing the story the right way.
Because of this, the writers spent more time on the final episode than on any other episode in the show’s history. The goal was simple but important: to give fans a strong and emotional ending.
This behind-the-scenes look shows how much care the Duffer Brothers are putting into the final moments of Stranger Things, even under intense pressure.
In the end, this behind-the-scenes detail shows how much pressure and care went into making the last chapter of Stranger Things. Even without a finished script at the start, the creators stayed focused on giving fans a strong and meaningful ending. The long writing time and honest struggles shared in the documentary prove that the team wants the finale to feel emotional, complete, and unforgettable.
