Our first look at Stranger Things Season 4 was revealed last week, with confirmation that Jim Hopper--aka "The American"-- was alive and stranded thousands of miles away from home. The new season is now in production and some new behind-the-scenes images have been revealed.

　　While the location of Hopper's snowbound prison was not named in last week's teaser, it's very likely to be set in Russia, given the title of the video was "From Russia with Love." Netflix has confirmed that some of the new season has been shot in the Lithuanian city of Vilnius, at 115-year-old Lukiškes Prison. The streaming giant has also released some behind-the-scenes images from the shoot, which you can check out below.

　　Stranger Things director Shawn Levy has also spoken about filming in Vilnius and preparing for last week's reveal. "My adventure here in Lithuania in bringing the reveal of the 'American' to life has been a huge challenge but an even bigger inspiration," he said. "We are so thankful to the city of Vilnius and the beautiful country of Lithuania for their hospitality. [Creators Matt and Ross Duffer] and I have been working alongside the brilliant Netflix team for months to pull off this surprise. All the hard work was worth it, however, to bring our fans--the greatest fans in the world--this epic reveal they've been hoping and waiting for. And this is only the beginning."

　　Stranger Things Season 4 does not yet have a release date. However, back in December, the Stranger Things writers revealed that the new season will arrive this year via a cryptic tweet, proclaiming that "we're not in Hawkins anymore." With production underway, there is a good chance Season 4 of Stranger Things will arrive in November or December on Netflix.
