Horror Movies You Never Realized Were In The Same Universe

There's no shortage of shared universes in film and television. The Marvel Cinematic Universe (MCU) and the DC Extended Universe (DCEU) are two of the most prominent examples of this connected approach to storytelling, but there are also the Tarantinoverse and Kevin Smith's View Askewniverse among many others that pervade the pop culture landscape (with plenty more on the way). While it can be easy to dismiss the concept of a shared universe as a mere fad, something that the entertainment industry can exploit to squeeze more money out of fans, the truth is that done correctly, shared universes allow for more complex and layered storytelling. Also, shared universes are a ton of fun for audiences. Viewers who've paid close attention to their favorite movies and shows will be rewarded when the small details from one story appear in and even impact another story, setting up the possibility of different characters and worlds coming together later.

With major studios plotting out how their existing properties can be expanded into other stories and media, it's easy to forget that there have been quite a few other shared universes already. Surprisingly, the horror genre has been playing with the idea of having many of its most popular characters existing alongside one another for quite a while — well before the release of such crossover films as "Freddy vs. Jason" and "Alien vs. Predator." If you want a list of the horror movies you never realized were in the same universe, then read on.

"Ring" (also known as "Ringu") is a 1998 cinematic adaptation of the 1991 novel by Koji Suzuki. The film follows a reporter who is looking into an urban legend about a videotape haunted by the vengeful spirit of a young girl named Sadako Yamamura that kills anyone seven days after viewing it. Several sequels followed, and there was an American remake, 2002's "The Ring," starring Naomi Watts. "Ju-On" is another long-running Japanese horror film franchise that got its start from a series of novels. The first film in the series was released in 2002 and told the story of a social worker who is plagued by two malevolent spirits (Kayako and her son Toshio) when she visits a home with a violent history. Like "Ringu," "Ju-On" was followed by numerous sequels as well as a big-budget American remake in the form of 2004's "The Grudge," starring Sarah Michelle Gellar.

America isn't the only country that likes to take its film franchises and crash them into one another, as the primary ghosts from both of these Japanese horror series would eventually meet in 2016's "Sadako vs. Kayako." The film follows two college students who, out of curiosity, unleash Sadako's evil spirit and must combat her with another evil spirit — that of Kayako. Response to "Sadako vs. Kayako" from both audiences and critics was lukewarm at best, so don't expect these two ghosts to step into the ring again anytime soon.

The late, great actor Dick Miller has made appearances in countless classic films, including "The Terminator," "Gremlins," "The 'Burbs," and many more. While he rarely played leading roles, his distinctive down-to-Earth demeanor and signature gravelly voice always made welcome additions to any film he graced. However, did you know Dick Miller's character Walter Paisley was the linchpin of a whole cinematic universe that spans decades?

The debut of Miller's Walter was in Roger Corman's 1959 horror-comedy, "A Bucket of Blood," wherein he's a busboy at a pretentious beatnik café who soon attracts acclaim for his statues. His "statues," however, are actually the corpses of people he's murdered and covered in clay. While Walter committed suicide at the end of the film, he apparently recovered and was reprised by Miller in Joe Dante's werewolf satire, "The Howling," as the owner of an occult bookshop. Dante brought Walter back again for his segment in "Twilight Zone: The Movie," which saw him returning to the hospitality business as the owner of a diner where his attempts to flirt with a customer are thwarted by a call from his wife. However, Walter's next appearance is as a janitor in 1986's "Chopping Mall," which follows a group of teenagers who spend the night in a shopping mall with a security detail of a trio of high-tech robots that eventually go on a rampage. Poor Walter gets electrocuted by one of the killer 'bots, but he's died before and gotten over it and would go on to appear in other horror films like "Night of the Creeps" and "Hanukkah."

"Jaws" is a landmark film for several reasons: It was Steven Spielberg's first big success, it launched the concept of the summer blockbuster, and its theme (composed by the legendary John Williams) is one of the most iconic in cinema history. The movie was such a hit that it led to three sequels, none of which lived up to the greatness of the original. Like many trendsetting movies, "Jaws" inspired a host of other "animals attack innocent people" movies. While most of these films were cheap imitations, the best of the lot is Joe Dante's 1978 film, "Piranha," as it treated the concept with a sly sense of humor that still holds up well today. It was even loosely remade in 2010 as "Piranha 3D" by horror director Alexandre Aja.

The through-line that joins the world of "Jaws" to that of "Piranha 3D" is Academy Award-winning actor Richard Dreyfuss, who played oceanographer Matt Hooper in the former and reprised the character in the latter. While Dreyfuss may be credited as "Matt Boyd" in "Piranha 3D," the actor confirmed who he was really playing in an interview with Hollywood News, saying, "I play Matt Hooper. I play the older Matt Hooper, who escaped being eaten by the shark and is now eaten by a bunch of piranha fish." It's a nasty end for the character, but at least the actor's payment was a donation to his civics education project, The Dreyfuss Initiative.

The Necronomicon is the creation of influential early-20th century horror author H.P. Lovecraft. An ancient grimoire of horrible spells, the Necronomicon would later be used by countless other horror authors and even make appearances in cinema. A version of the book called the Necronomicon Ex-Mortis plays a major role in the "Evil Dead" films and was said to deal with "demons and demon resurrection and those forces which roam the forest and dark bowers of man's domain." Of course, when a group of young people decides to have some fun with it, they accidentally awaken an eldritch and malevolent force that terrorizes its victims across three movies. 

However, this version of the Necronomicon wasn't just confined to the "Evil Dead" series, as it would later appear in 1993's "Jason Goes to Hell: The Final Friday," seemingly implying that Jason Voorhees' resurrection may have gotten an assist from the book. It would also go on to make another appearance in 1994's "Pumpkinhead II: Blood Wings," in which it was seen in the house of the old witch. It makes perfect sense for the Necronomicon Ex-Mortis to show up in movies that involve bridging the gap between the living and the dead, but that would also mean that the tome's owners also check it out from the same library. (Bonus connections: Freddy Kreuger's glove can be seen in the background in "Evil Dead 2," although this is more of a callback to when Wes Craven had "The Evil Dead" playing on a TV in "A Nightmare on Elm Street.")

"Behind the Mask: The Rise of Leslie Vernon" wasn't the first film to imply that cinema's biggest baddies all existed in the same universe. Those seeds were planted years earlier. The ending of 1993's "Jason Goes to Hell: The Final Friday" sees the bladed hand of Freddy Kreuger (Robert Englund) exploding out of the ground to presumably take Jason Voorhees' (Kane Hodder) mask to hell. While that little tease would ultimately pay off in 2003's "Freddy vs. Jason," the connections between those two villains were established in 1998's "Bride of Chucky" in a scene that features a police storage locker that just happens to have Freddy's glove and Jason's hockey mask.

But wait, there's more! Also seen in that police storage locker are the mask of Michael Myers (from the "Halloween" series) and Leatherface's chainsaw. This scene opens up countless possibilities of a wider shared universe that's far more sprawling than we might realize. For example, if the Necronomicon Ex-Mortis from the "Evil Dead" franchise exists in the "Friday the 13th" franchise as we previously established, then that means it also exists in the "Child's Play," "Nightmare on Elm Street," and "Texas Chainsaw Massacre" franchises as well! Heck, maybe the chainsaw Ash uses to replace his hand was purchased from Stretch. Think about it!
