Angel Heart (1987)
94% fit113 min · IMDb 7.2 · RT 82%
Alan Parker turns a missing-singer case into investigator horror that keeps closing in on Harry Angel himself. The casework is tactile, the clues grow occult through voodoo circles and dirty back rooms, and the final turn makes the whole hunt feel intimate in the worst way. Dread settles deep long before Louis Cyphre starts spelling things out.

2. The House of the Devil (2009)
95 min · IMDb 6.3 · RT 86%
Ti West trades formal casework for Samantha's lonely clue-gathering inside one bad babysitting job. It still plays like investigator horror in miniature, with every hallway, phone call, and closed door turning tiny clues into occult dread. The slow build is patient enough that the danger feels intimate before the film ever raises its voice.

3. The Ninth Gate (1999)
133 min · IMDb 6.7 · RT 44%
Dean Corso works like a shabby investigator, chasing rare-book clues across libraries, manors, and fires instead of crime scenes. Roman Polanski keeps the casework cool and methodical as the occult details pile up, which makes the threat feel strangely intimate by the end. The dread sits deep because the movie never hurries to explain what Corso has stepped into.

David Prior starts with missing-person casework and then lets the investigation sprawl into cult territory, urban legends, and something far older. James Lasombra moves through this investigator horror like a man getting trapped by his own clues, and the story keeps turning more intimate as the search widens. Its dread settles deep because every answer opens a larger occult wound.

This one drops the detective angle and turns occult casework inward, locking you in with Sophia Howard and Joseph Solomon as they test every step of a ritual. The clues are emotional, practical, and spiritual at once, so the horror feels painfully intimate from the start. The slow pace lets dread settle deep inside each repeated task and setback.

The Outsider
This is investigator horror built around a child murder case that keeps sliding from evidence and interviews into something ancient and malignant. It matches the hub with its patient dread and shadowy pacing, and it lines up with Longlegs through the way casework becomes personal as the evil behind the clues gets harder to explain away.

A restoration job turns into a slow, obsessive investigation, with recorded clues pulling the lead deeper into a cult story that feels increasingly intimate and dangerous. It fits Spooky Slow-Burn Horror through its creeping unease and occult trail, and it shares Longlegs' mix of methodical clue-following and deep-set dread.
Netflix
The Fall of the House of Usher
This series uses depositions, old crimes, and a mounting body count to unfold like a cursed case file, with each answer pointing toward rot, ritual, and family guilt. It fits the hub because the dread builds steadily across the season, and it echoes Longlegs in the way investigation opens the door to something personal, uncanny, and corrupting.
Netflix
Night Film
by Marisha Pessl
Like Longlegs, this follows an investigator whose case stops being professional and starts consuming his private life, as a young woman's death leads back to a hidden cult-horror director and a troubled father-daughter bond. Its document-heavy search through rumor, subculture, and unstable reality builds dread in a slow, lingering way.

Common questions about movies like Longlegs (2024)
What is the best movie like Longlegs (2024)?
Based on our analysis, Angel Heart (1987) is the closest match with a 94% fit score. See the full breakdown above for why it earned the top spot.
Which of these can I watch with a partner who likes mysteries more than gore?
The Ninth Gate is the easiest sell because the rare-book hunt plays like a devilish detective story. Angel Heart also works if your partner can handle grim murders and sexual material. Save The Empty Man and A Dark Song for someone who actively wants deep dread.
Which one should I avoid if occult material or serial-killer style violence really gets to me?
A Dark Song and The Ninth Gate stay closest to ritual and devil lore, so they hit hardest if occult material bothers you. Angel Heart has the grimiest murder trail, and The Empty Man piles on cult behavior. The House of the Devil stays restrained for a while, then turns nasty fast.
What should I pick if I want eerie rather than crushing?
The Ninth Gate is your best bet. It keeps a cool, curious feeling through most of its book chase, even when the devilish clues stack up. A Dark Song is heavy but lands with more release than Angel Heart or The Empty Man.
Which is the easiest weeknight watch, and which needs my full attention?
The House of the Devil is the simplest weeknight pick at 95 minutes, with one house and a very clean setup. The Ninth Gate and The Empty Man need more patience because their clue trails are longer. A Dark Song also wants focus, since every ritual step matters.
Which feels most like a detective story, and which feels most like pure ritual horror?
Angel Heart and The Empty Man lean hardest into investigation, with interviews, missing people, and lead-chasing driving the plot. A Dark Song is almost pure ritual from the opening minutes. The House of the Devil is a housebound creep-out, and The Ninth Gate is the most bookish of the group.
Where should I start if I'm new to slow-burn occult horror?
Start with Angel Heart if you want the clearest bridge between detective work and supernatural rot. Pick The House of the Devil first if you prefer a shorter, cleaner setup and one central location. Save The Empty Man for later, because its scale and ideas are wider and stranger.
