As we get ready to step back into Hawkins for the fifth and final season of Stranger Things, it’s now fall of 1987 in Indiana — a new year, with a new set of timely pop culture references that might turn up on the show. The real world’s film, music and TV has a way of leaking into the adventures of Eleven, Mike, and the rest of the gang, from season three’s moment where Max, Lucas, Will and Mike sneak into a special screening of 1985’s George A. Romero zombie classic Day of the Dead, to season four’s repeated use of Kate Bush‘s 1985 hit “Running Up That Hill.” Though we won’t know for sure what pop culture will feature in the new season until we watch, it might be handy to flashback to the most popular films of fall 1987. These films hit number one at the box office throughout the season — and one absolutely dominated theaters for months.
