David Harbour’s Jim Hopper is back in the saddle for a fourth season of Stranger Things. This time, according to a teaser trailer, he’s imprisoned in an obscure Russian region. “We’re excited to officially confirm that production on Stranger Things 4 is now underway — and even more excited to announce the return of Hopper. Although it’s not all good news for our “American”; he is imprisoned far from home in the snowy wasteland of Kamchatka, where he will face dangers both human…and other. Meanwhile, back in the states, a new horror is beginning to surface, something long buried, something that connects everything,” creators The Duffer Brothers wrote.
