From the beginning, Stranger Things has been all about '80s cultural references. One might argue the show's initial pitch, "Steven Spielberg meets Stephen King," bakes the idea that this is a patache of '80s media tropes into the show's DNA. From the first season onward, one of the most fun games for nerds who love it is picking out all the references to other media in the series' episodes. These Stranger Things Season 3 easter eggs are proof the show has a long way to go before it runs out of material.
The most significant reference this season is, naturally, Back To the Future. The first movie in this nerd touchtone franchise arrived on the Fourth of July weekend 1985, the exact point when the show is set. Not only is it playing in theaters, and discussed by a very stoned Steve and Robin, but there are tons of extra references thrown in as well. El's skateboard is the same one as Marty McFly, and the clock in Mrs. Driscoll's house is the same owned by Doc in the movie. Huey Lewis gets included in the season premiere soundtrack. And even though Billy might not be going 88 miles an hour as he tries to drive into the disabled station wagon outside Starcourt, the shot is almost identical to Doc and Marty's first ride through their own mall parking lot in the film.
Let's go over the rest of the easter eggs in Stranger Things Season 3.
