There's no premiere date in sight for the fourth season of Stranger Things [1], but that doesn't mean things aren't happening behind the scenes! In a sweet surprise for fans, Netflix announced the start of production for the upcoming instalment [2] with a video of the cast gathering together, and we can't lie, it's gotten us in our feelings a bit. The entire cast comes together like a family at a big reunion, and it makes us even more excited for season four [3] than we were before. And everyone looks so grown up!

We already knew that Hopper was alive [4] thanks to the teaser [5] dropped on Valentine's Day, but seeing David Harbour walk into the table read rocking his Russian-forced haircut makes it 10 times more real! And you can't miss the inclusion of Priah Ferguson and Brett Gelman, who were recently upgraded to series regulars [6] for their roles as Erica Sinclair [7] and our favourite conspiracy theorist, Murray Bauman, [8] respectively. Watch the cute video ahead, and be on the lookout for more sneak peeks behind the scenes as Stranger Things [9] season four kicks off production!
