17 '80s-Inspired Easter Eggs in "Stranger Things" Season 4

Throughout the season, different characters reveal just how much they know about some of the most beloved (and cult-favorite) pop culture properties of the time. Jonathan notes that "Police Academy 3" is currently playing in theaters, while Nancy has a Tom Cruise poster on her wall, with the season taking place right around the same time that his breakout hit "Top Gun" came out. Will is in on it too, with a "Little Shop of Horrors" poster in his room.
