Stranger Things creators Matt and Ross Duffer have addressed those spin-off rumours.
The pair first discussed it in an interview with Deadline; without revealing any details, Matt told the publication, "I'm so, so excited about it. But it is not… It's going to be different than what anyone is expecting, including Netflix."
The conversation sparked rumours that it might be a spin-off centred on one of the characters.
In an appearance on Josh Horowitz's Happy Sad Confused podcast, the brothers reiterated that it would be 100% different from the science fiction show.
"I've read these rumours that there's going to be an Eleven spin-off, that there's going to be a Steve and Dustin spin-off or that it's another number. That's not interesting to me because we've done all that. We've spent, I don't know how many hours exploring all of that. So it's very different," said the creators per Complex.
They added: "The most important connective tissue, I would say, is the storytelling sensibility of it. There is story that connects to the Stranger Things world, but it really is more about how we're telling that story."
In February, the pair announced that Stranger Things would end with season 5. In an open letter to the fans, they teased that "there are still many more exciting stories to tell within the world of Stranger Things; new mysteries, new adventures, new, unexpected heroes."
