Descending into Madness: 20 Films That Captivate the Journey to Insanity

Horror films are moving away from schlocky jumpscares and branching into sophisticated, elevated horror. One of the most popular avenues for directors to explore is the descent into madness trope. This happens when a character becomes obsessed with a thought or idea. An innocent infatuation can quickly turn into a heart-pounding danger as the audience can't help but watch the disaster unfolding on the screen. 

Here are 20 movies that perfectly exemplify the journey into madness.

1. Pearl

Mia Goth is Pearl, a wannabee starlet capable of going to great lengths to achieve the dream she wants. Released as a prequel to the slasher homage XPearl revolved around a young woman destined for the big screen, or so she thought. Pearl starts as a shy, kind girl living on a farm with her sick father and overbearing mother. Soon, the farmhouse's confines and Hollywood's outstretched arms absorb her every thought. Pearl descends into a swirl of madness.

Goth’s performance alone makes her one of the best new horror names in the 2020s. 

2. Midsommar

When Dani’s parents and sister all die in a murder-suicide, Dani resorts to the only remaining support system: her estranged boyfriend, Christian. Dani, Christian, and their friends all travel to a Swedish ritual on behalf of their friend, Pelle. A peaceful outing between friends and family spirals into a terrifying cult celebration.

Dani’s depression manifests into terror, but you won’t be able to peel your eyes off Florence Pugh’s masterful performance, no matter how brutal the film gets — and it gets brutal.

3. Saint Maud

Saint Maud follows a nurse-turned-religious zealot, determined to save everyone around her. Saint Maud’s release date was pushed back and bounced around during COVID-19. The incredible film never received the official theatrical release it deserved (although it did have a limited release in 2021). Still, that didn’t stop this religious tale from searing into the minds of horror enthusiasts everywhere. 

Saint Maud delivers one of the best stories about religious obsession ever. Plus, the film's final scene stays burned in your brain forever.  

4. Climax

Gaspar Noe’s avant-garde dance is a literal descent into madness. When a group of dancers ingests LSD-laced punch, they embark on a trip that doesn’t end swimmingly. Stakes rise, and tensions run high while the troupe tries to uncover the culprit that laced the punch. 

What elevates the dive into instability is that Climax begins at the end. The film starts with a credit roll before launching into video interviews with the dancers. The color schemes and editing sequences make the viewer feel like they are on the same acid-fueled trip as the dancers. Climax is definitely not for everyone.

5. We Need To Talk About Kevin

This movie is eerie for a few reasons.  Ezra Miller approaches Kevin with such deftness it becomes difficult to discern fiction from reality. We Need to Talk About Kevin nods to Kevin’s upbringing, how the parents tried to assuage him and give him an outlet for expression, but he is pure evil. 

We witness Kevin’s actions through his mother’s viewpoint. Tilda Swinton’s character harbors a ton of internalized guilt, resentment, and shame around Kevin. This film opens up two distinct descents, Kevin’s descent into evil and his mother’s descent into incessant guilt. 

6. Black Swan

The world of competitive dance is cutthroat- sometimes literally. In this critically acclaimed film, Nina, played by Natalie Portman, begins to experience intense hallucinations while rehearsing for a leading role in the ballet Swan Lake. As the opening night of the show approaches, Nina's hallucinations escalate, ultimately leading her to physically attack the doppelganger plaguing her waking moments.

Black Swan ends on a cliffhanger, leaving the audience to wonder if Nina escaped the madness surrounding her or if she succumbed to the pressure of being on stage.

7. Requiem for a Dream

Drug addiction can send the most sane person down a wormhole of madness. In Requiem for a Dream, the audience witnesses the descent of the four main characters as their drug use goes from bad to worse.

The realistic nature of this movie makes it all the more intense, and while you watch the addicts struggle on the screen, you can't help but be reminded of the ones struggling in real life.

8. The Machinist

As the movie goes on, Trevor frantically tries to chase down his delusions, only to be confronted with them in a way he never expected.

9. The Lighthouse

When a new employer tells you you're replacing someone who went insane on the job, you should probably heed the warning and look for another place to earn some cash. Ephraim Winslow does not.

Beautifully acted by Robert Pattinson and Willem Dafoe, this movie explores the impact of isolation on the human mind.
