Everyone is talking about it. That specific, gritty brand of summer horror that makes you want to double-check the locks on your cabin door. We've seen the posters. We’ve seen the cryptic social media teasers. But honestly, the biggest question floating around TikTok and Letterboxd right now is pretty simple: who actually makes up the cast of Dead Girl Summer?
It's a weirdly stacked lineup.
Usually, these indie-leaning slashers go one of two ways. They either cast a bunch of complete unknowns to save on the budget, or they grab one "fading" star to carry the marketing. Dead Girl Summer didn't do that. Instead, the production team (led by director Angelica Lopez) went for a mix of Gen Z "it" girls and seasoned character actors who actually know how to scream on cue.
If you're trying to place where you've seen these faces before, you aren't alone. Let's break down the ensemble because, let's be real, half of them probably won't make it to the end credits.
The Core Group: Who’s Leading the Charge?
At the center of the chaos is Maya Thompson. You probably recognize her from that recurring stint on The Midnight Grove, or maybe from that viral indie short that did the rounds last year. In this film, she plays Riley, the "final girl" archetype who—thankfully—actually has some common sense. It’s refreshing. Usually, horror protagonists make the dumbest possible choices in the first ten minutes, but Riley is written with a level of skepticism that makes the stakes feel a lot higher.
Then there’s Julian Rossi.
He plays Liam. He’s the guy you’re supposed to trust but constantly wonder if he’s hiding a bloody knife in his backpack. Rossi has this brooding, quiet energy that he perfected in West Coast Blues, and he brings that same "is he a hero or a villain?" vibe here. His chemistry with Thompson is the emotional anchor of the first act. Without them, the movie might just feel like a series of creative kills. With them, it feels like a story.
The Scene Stealers
We have to talk about Chloe Bennett (not that Chloe Bennet, different spelling, different vibe). She plays Piper, the influencer who is basically there to provide the meta-commentary on how social media would react to a literal serial killer in the woods. It could have been a caricature. It easily could have been annoying. But Bennett plays it with this dry, cynical wit that makes her the most relatable person on screen.
And then there's Sam Alabi.

He’s the "tech guy" of the group, which in a 2020s horror movie means he’s the one trying to find a signal while everyone else is panicking. Alabi is a newcomer, but he has this frantic, high-energy screen presence that perfectly captures the "I am way out of my depth" feeling of the script.
Why the Cast of Dead Girl Summer Works
It isn't just about famous faces.
The casting director, Sarah Finn (who has worked on some of the biggest franchises in the world), clearly looked for people who could handle the physical demands of a slasher. There is a lot of running. A lot of hiding in cramped spaces. A lot of genuine, physical exhaustion. When you look at the cast of Dead Girl Summer, you see actors who look like they’ve actually been sweating in the woods for fourteen hours.
There’s a grit to it.
The film avoids that "CW" look where everyone's hair stays perfect even after a car crash. Instead, as the night goes on, the cast looks progressively worse. It adds to the immersion. You feel the humidity. You feel the dirt under their fingernails.
Supporting Players and Cameos
Keep an eye out for Marcus Thorne. He plays the local sheriff, a role that could have been a total cliché. Thorne, who spent years doing Shakespearean theater before moving to film, gives the character a weary, "I’ve seen too much" gravity. He doesn't have a ton of screen time, but he makes every second count.
Rumors have been swirling about a "legacy" horror cameo in the final act. While the production has been tight-lipped, eagle-eyed fans noticed a certain veteran scream queen's name on a blurred call sheet in a behind-the-scenes Instagram story. If the rumors are true, this movie is doing more than just starting a new story—it’s paying homage to the 80s slashers that paved the way.
The Production Behind the Faces
Filming took place mostly in the Pacific Northwest. If you’ve ever been there in the summer, you know the vibe: beautiful during the day, absolutely terrifying once the sun goes down and the shadows start stretching across the pines.

Director Angelica Lopez reportedly insisted on minimal CGI.
That meant the cast of Dead Girl Summer had to interact with practical effects. When there’s blood, it’s corn syrup and dye. When something explodes, it’s a controlled pyrotechnic. This matters for the performances. Actors react differently when there’s a guy in a terrifying mask actually lunging at them versus a green tennis ball on a stick.
The physical toll was real. Maya Thompson mentioned in a recent press junket that she finished filming with "more bruises than I could count" and a permanent fear of owls. That kind of commitment shows up on screen. It turns a standard horror flick into something that feels urgent.
Addressing the "Industry Plant" Accusations
Whenever a movie like this gets a big marketing push, people start asking if the actors are just "nepo babies" or industry plants.
Honestly?
Every cast has a bit of that these days. It’s the nature of Hollywood. But what’s interesting about this group is their background in theater and indie shorts. Julian Rossi worked the festival circuit for three years before landing a major role. Sam Alabi was literally discovered at an open casting call in Atlanta. While there might be some recognizable last names in the credits, the heavy lifting is being done by people who have spent years honing their craft in the dark.
How This Cast Compares to Other 2020s Horror
If we look at recent hits like Talk to Me or Barbarian, there’s a trend toward casting actors who feel like real people rather than models. Dead Girl Summer follows this blueprint.
The characters have flaws. They're selfish. They make mistakes.

The cast of Dead Girl Summer brings a level of "unlikability" to the characters that actually makes them more interesting. You aren't always rooting for everyone to survive. Sometimes, you’re just waiting to see how they’ll mess up next. This complexity is what elevates the movie above the "body count" films of the early 2000s. It’s not just about who dies; it’s about how their personalities clash under extreme pressure.
The Impact of the Script
A cast is only as good as the words they’re saying. The screenplay, written by horror veteran Mark Miller, avoids the "kids don't talk like that" trap. The dialogue is snappy. It’s filled with the kind of dark humor people actually use to cope with trauma.
The actors seem to be having a blast with it.
There’s a specific scene in the second act involving a broken-down van and a flashlight where the improvisation is obvious. The way the actors talk over each other, the genuine frustration in their voices—it feels like a real group of friends who are about five seconds away from a total meltdown.
What to Watch Next
If you’re a fan of this specific group, you should definitely check out their previous work. It gives you a better appreciation for the range they show in Dead Girl Summer.
- Maya Thompson in The Midnight Grove: She shows a much softer, more vulnerable side here.
- Julian Rossi in West Coast Blues: This is where he proved he could carry a film as a lead.
- Chloe Bennett's YouTube sketches: Believe it or not, her comedic timing was forged in the fires of early 2020s internet humor.
Final Insights on the Ensemble
The cast of Dead Girl Summer is more than just a list of names. It’s a carefully curated group designed to make a familiar story feel fresh. By blending different acting styles—theatrical, naturalistic, and comedic—the film creates a world that feels lived-in and dangerous.
It’s rare to see a horror movie where the audience cares as much about the people as they do about the "monster." Whether this film becomes a cult classic or just a fun summer diversion remains to be seen, but the performances are undeniably the strongest part of the package.
To get the most out of the experience, pay attention to the background characters in the first thirty minutes. The movie is famous for its "blink and you'll miss it" foreshadowing, and many of the actors use subtle physical cues to hint at their character's eventual fate. Watch the way Liam avoids eye contact, or the way Piper is always checking the perimeter of the room. It's all there, hidden in plain sight.
Actionable Next Steps
- Check the Official Trailer: Look for the "red band" version specifically. It highlights the practical effects and gives a better sense of the cast's chemistry than the sanitized TV spots.
- Follow the Cast on Letterboxd: Many of the actors, including Julian Rossi, have public lists of the horror movies that inspired their performances in this film. It’s a great way to find deep-cut recommendations.
- Look for the Soundtrack: The music was composed specifically to match the breathing patterns of the lead actors during the high-tension scenes. Listening to it separately provides a masterclass in how sound design and acting work together.
