Casper Kelly's Killer Unicorn 'Buddy' Hits Theaters Thursday
Before Casper Kelly made a feature film, he broke the internet with four minutes of television. "Too Many Cooks," his 2014 Adult Swim short, started as a cheery sitcom credits parody and descended into something genuinely disturbing — a mass-media nightmare that nobody saw coming and nobody could stop watching. Over a decade later, Kelly is back with Buddy, and the only question is whether your childhood memories will survive it.
What Is Buddy?
Buddy arrives in theaters August 28 from Roadside Attractions and Saban Films. The premise is deceptively simple: you're on the set of a beloved children's program called It's Buddy!, hosted by an aggressively cheerful neon-orange anthropomorphic unicorn. One day, during a live taping, a child performer refuses to participate. The music stops. The studio doors lock. And Buddy — that grinning, brightly colored beacon of preschool nostalgia — decides to start hunting.
It is, in essence, "What if Barney went bad" as a full-length horror film, and the Sundance Film Festival audience that caught its world premiere earlier this year hasn't been able to stop talking about it since. Bloody Disgusting called it "messy, singular killer-unicorn madness" — and they meant it as a compliment.
The Cast Behind the Chaos
Kelly assembled a genuinely wild cast to deliver his vision. Cristin Milioti (The Resort, Palm Springs) leads as a human caught inside the nightmare, joined by Michael Shannon, Patton Oswalt, and Topher Grace. Keegan-Michael Key voices Buddy himself — a choice that makes terrible, perfect sense once the film gets going.
The film was shot entirely in Cleveland, and the production design leans hard into the uncanny valley between children's entertainment and pure dread. Think primary colors doing things primary colors should never do.
From Too Many Cooks to Feature Horror
The road from a viral Adult Swim short to a feature-length horror film is not a common one, but it suits Kelly's sensibilities perfectly. Both projects share the same core obsession: what happens when the comforting grammar of mass-market entertainment turns against you?
"Too Many Cooks" worked because it exploited your trust in TV formulas. Buddy does the same thing with children's programming — specifically, the kind of programming designed to feel safe, inclusive, and endlessly gentle. The horror isn't that Buddy exists. It's that Buddy was supposed to be the safest thing in the room.
Kelly began developing the project after years of exploring what he calls the dark underbelly of optimized media, and his feature debut premiered in the Midnight section of Sundance 2026 to strong word-of-mouth from the horror crowd.
A Game Boy Color Game? Yes, Really.
In what may be the most on-brand marketing partnership of the decade, Buddy is also getting a physical Game Boy Color game — an actual cartridge that plays on original hardware.
Developed by PlayInstinct and published by ModRetro (makers of the ModRetro Chromatic handheld), Buddy: The Video Game drops Q4 2026 and includes four modes: a story mode where you choose to appease or defy Buddy while navigating the film's events; a survival mode where you're hiding from Buddy; a mode where you play as Buddy hunting down children; and a mini-game mode pulled directly from the show-within-the-film (dancing, painting, dusting, riding — rendered in charming pixel-art children's-show aesthetics before things inevitably go wrong).
It's a physical cartridge. It runs on a Game Boy Color. It comes out in Q4. This is real.
Should You Go See It?
If you liked M3GAN, Violent Night, Skinamarink, or any horror film that weaponizes something that should feel safe — yes, absolutely. Buddy has that same current running through it: the specific horror of a friendly face that keeps smiling after it shouldn't.
Roadside Attractions is giving it a wide theatrical run starting Thursday, August 28. No streaming date has been announced, which means the theatrical window is your only shot to see Buddy in a dark room with strangers — which is, honestly, exactly how this movie should be experienced.
Just don't bring a child. They'll ask too many questions, and some of them you won't be able to answer.
