Series co-creator Ross Duffer revealed Friday that he and brother Matt Duffer cast their high school drama teacher, Hope Hynes Love, in a pivotal season 5 role as Hawkins Elementary School teacher Miss Harris.

Stranger Things Season 5 features a quest for 12 children, for reasons that are currently uncertain. At the very least, this certainly parallels “Inferno.” Worst-case scenario, that’s Vecna’s goal; to stabilize the gates between Hawkins and the Upside Down through the deaths of innocents.

Just because 'Stranger Things' is coming to an end doesn't mean season 5 didn't find a way to expand — and recast — with some new characters

Spoiler alert! Everything you need to know about "Stranger Things" Season 5 Episode 4, including that massive Will Byers cliffhanger.

After a three-year wait, the Netflix juggernaut gave us three cliff-hangers, a movie-scale battle sequence, and so much more. Anthony Breznican breaks down what it all means.

Stranger Things: The First Shadow was written by Stranger Things staff writer and story editor Kate Trefey. Interestingly, Trefey is credited with writing a single episode in the show’s fifth and final season: Stranger Things Season 5 Episode 6 “Escape from Camazotz,” set to debut on Christmas Day.

“It was a whiplash of a reveal for me,” Schnapp, 21, told Entertainment Weekly during an interview published alongside the release of “Stranger Things” Season 5, Volume 1 on Friday. But according to show creators Matt and Ross Duffer, Will hasn’t suddenly become a second Eleven. His powers come from somewhere much darker.

Netflix has unveiled Stranger Things season 5 episode 1 to fans in a super secret screening – and according to them, we’ll be ‘surprised’ by what’s in store.
