Netflix recently put out the new trailer for Stranger Things season four, which introduced the Creel Family home, which is owned by the character played by horror legend Robert Englund in the series.
Of course Millie Bobby Brown has a deal with Netflix, which will see her not only return as Eleven in Stranger Things but also reprising the title character in Enola Holmes, so there is every likelihood that she would be on board for a Stranger Things spin-off centered on main character Eleven with the Duffer Brothers.
He however continued, when talking about Stranger Things specifically, to say that the show is currently “a franchise being born” and also hinted that there were “spin-offs” being considering.
There are also a few options already out there that could be explored in future branches of the sci-fi horror series.
