The Upside Down is made of bubble wrap
In a section of the book that is, fittingly, upside down, special effects coordinator Caius Man reveals that bubble wrap and sheet plastics that were melted and painted helped create the creepy vines that populate the Upside Down. “We spent three months, closer to four, probably, fooling around with every chemical and flexible stretchy thing and meltable thing we could get our hands on,” Man explains in the book.
In Season 2 when many of the characters visit the tunnels from the Upside
A teaser released this year showed Steve and a new character played by Maya Hawke working at Hawkins’ new Starcourt Mall. The book confirms that Steve is now a high school graduate, it’s the summer of 1985, and our burgeoning couples from Season 2 (Mike and Eleven, and Max and Lucas) are official. The new season will follow the teenagers’ raging hormones, but it also takes inspiration from classic body horror such as Dave Cronenberg’s “Shivers.”
Ross calls the season the “most fun” but also the “grossest.” The book also confirms that the Mind Flayer monster is definitely not gone.
