Some revelations from the Duffer Brothers:
- Steve was originally going to die during season one.
- Lonnie was going to be with Nancy and Jonathan during the season one climax.
- A 20-page draft was created when Netflix asked about the long-term mythology and that included Vecna.
- They filmed at an actual prison in Lithuania in real snow, which means Harbour was actually running barefoot in snow.
- Ryder believes Eleven would drag Hopper to Beetlejuice.
- Steve was originally going to be a swimmer who wore speedos for swim meets, but it was cut because they couldn't get a gym pool. Keery trained to get ready for that until he found out it was cut out, but it finally paid off for this season.
- Quinn sees Eddie as a character out of a Scooby-Doo story...as if directed by Steven Spielberg and John Carpenter.
