Netflix has dropped a video preview of the upcoming stage play “Stranger Things: The First Shadow,” which begins performances this month in London.“We were in the middle of breaking Season 4 with our writers, and we started going, ‘OK, well, there’s definitely more story to tell here,’” says Ross Duffer, who co-created the sci-fi series with his brother, Matt, in the featurette. “We wanted to tell an original story set in the ‘Stranger Things’ universe.”The all-new tale, written by series writer Kate Trefry, will be a prequel — so don’t come looking for Mike, Will, Dustin, Lucas or Eleven — partly about young Hopper and Joyce, played on the streaming show by David Harbour and Winona Ryder, respectively.Those roles will be taken on at the Phoenix Theatre by Oscar Lloyd and Isabella Pappas.
