“I think most would probably say it’s the scariest out of the previous three, which I love because it’s very fun to film,” Gaten Matarazzo, who plays Dustin Henderson 

The hit Netflix series is set in 1980s in the fictional Hawkins, Indiana, and follows various supernatural events that affect the town. 

The show stars Millie Bobby Brown, Finn Wolfhard, Caleb McLaughlin, Noah Schnapp, Winona Ryder, David Harbour and more. 

One of the biggest mysteries following the season 3 finale, which debuted in July 2019, was whether Jim Hopper (Harbour) was truly dead.  

Fans got a glimpse at the answer during the first teaser for season 4, which was released in February 2020 and showed Hopper in Russia after he seemingly vanished in a mysterious machine.

Netflix released the first trailer for season 4 in April 2022, and it looks like the Hawkins gang will need to start preparing for battle. "A war is coming.  

Your friends in Hawkins are very much in the eye of a storm," Dr. Owens warns Eleven at one point. "I don’t know how to say this other than just to say it — without you, we can’t win this war." 

The clip also teases a monster from the Upside Down, who appears to be some kind of hybrid Demogorgon, who states menacingly at the end of the trailer: "You have lost."
