Although she doesn't correct him in the scene, the goth girl whose costume Jonathan (Charlie Heaton) guesses is supposed to be a member of Kiss at "Tina's stupid party" is actually dressed as Siouxsie Sioux, front-woman of Siouxsie and the Banshees.
Steve (Joe Keery) and Nancy (Natalia Dyer) are dressed up as Tom Cruise and Rebecca De Mornay from Risky Business (1983).
The video camera used by Bob (Sean Astin) and Will (Noah Schnapp) is the JVC GR-C1, the same model used by Marty (Michael J. Fox) in Back to the Future (1985).
Will's costume is noticeably simpler than the others, due to the Byerses not having as much money as the other families in the show. In the previous episode you see Joyce making Will's costume at work, instead of buying one like the other parents did.
In an interview, Millie Bobby Brown said that she loved shooting scenes in the cabin with David Harbour, but like Eleven, she found the scenes of her alone incredibly boring.
