ABCs of Horror 3: “I” Is for Intruder (1989)

Paste’s ABCs of Horror 3 is a 26-day project that highlights some of our favorite horror films from each letter of the alphabet. The only criteria: The films chosen can’t have been used in our previous Century of Terror, a 100-day project to choose the best horror film of every year from 1920-2019, nor previous ABCs of Horror entries. With many heavy hitters out of the way, which movies will we choose?
Director Scott Spiegel’s Intruder, in a sentence, is like the greatest slasher film of 1981 to come out in … 1989.
In response to a statement like that, it’s perfectly understandable to ask how much difference such a relatively small gap in time would actually make. Film geeks and even general horror fans often think of the 1980s as a broad period that contained the slasher movie boom, without realizing quite how much that period is stratified into “early” and “late” eras, which catered to a rapidly evolving viewer base. Suffice to say, the state of the slasher film in the beginning of the 1980s was very different–much more grounded, sincere and earnestly shocked by its own bloodlust–than the more imaginatively silly excess and increasing self-parody that marked so many entries in the genre by the decade’s end.
Look no further for a case study in this phenomenon than a franchise like the iconic Friday the 13th, which kicked off the commercial slasher boom by luridly capitalizing on so many of the elements that Carpenter’s Halloween had helped to codify. In 1980, and through the first handful of sequels in 1981, 1982 and 1984, the series is content to hang around Crystal Lake and run through the motions without ever quite committing to killing off its hulking brute of an antagonist, recognizing that doing so would be discarding a potent cash cow. But after finally doing so in 1984’s Friday the 13th: The Final Chapter, the back half of the decade starts evolving the series in rapid, increasingly outlandish fashion. By 1986 (Part VI: Jason Lives), Jason Voorhees is now an indestructible, undead golem. By 1988 (Part VII: The New Blood), he’s being opposed by a telekinetic heroine, in a direct parody of Carrie. And in 1989 (Part VIII: Jason Takes Manhattan) he’s appearing to a young woman via empathic visions of his young, deformed self, even as he stalks high school students aboard a “cruise ship” to New York City. Even Camp Crystal Lake had finally been discarded, along with most semblances of what a Friday the 13th movie previously looked like.
Intruder, on the other hand, is a film you’d watch and swear that it had to be a relic of 1980 or 1981, only to be shocked that it rolled in at the same time as the likes of Halloween 5 or A Nightmare on Elm Street 5. It’s a throwback in all of the best ways: A single-location, low-budget slasher with a mystery killer and some of the most shockingly gory slayings (and ridiculous practical effects) the genre has to offer. At a time when most filmmakers working the genre had stopped attempting to genuinely shock anyone, Intruder was still going for the jugular.
