The Making of Stranger Things 5" on Monday, a behind-the-scenes documentary that follows the cast, crew and creators as they filmed the final season of the sprawling, 10-year series. The doc will premiere on the streamer on Jan.

The cast of Stranger Things break down in tears in the first look at a new documentary about the final season's production - with Millie Bobby Brown admitting 'I'm not ready to let go'.

Brown, who famously starred as the telekinetic teen for the show's five seasons, is the only person (aside from the Duffer brothers) who knows what really happened to her character.
