The video-store kid from Jönköping
David Fredrik Sandberg grew up in Jönköping, Sweden, making films with his dad’s VHS-C camera from the age of seven or eight. “They were usually violent,” he’s said. “They were often war movies. I remember making a Vietnam war movie in Swedish woods when I knew nothing about Vietnam.” As a teenager he worked in a video store and saved up to buy his own camcorder. His younger brother Joakim became a video game developer — creator of Iconoclasts — so the image-making gene ran in the family.
He met his future wife, Lotta Losten, at Torpa School when they were both around eleven. They went to Junedal School together. She’d become his star, his producer, his constant collaborator — the woman standing in the dark in Lights Out.
Sandberg’s twenties were the long apprenticeship: interning at Film i Jönköping, learning from mentor Svante Rosberg, making animated shorts and documentaries. Starting in 2006, he found an audience online for animated shorts like Vad Tyst Det Blev (1.7 million YouTube views), which led to animation consulting work on Swedish TV. Then he started posting no-budget horror shorts under the pseudonym “ponysmasher” — written, directed, produced, edited, and scored by himself, starring Lotta. The cast and crew, most days, was two people and a camera.
The work, film by film
Lights Out (2013) — the short — is three minutes long and perfect. A woman turns off the lights; a silhouette appears in the dark; she turns them on and it’s gone. That’s the whole movie, and it broke the internet. Hollywood producers Lawrence Grey and James Wan (Saw, The Conjuring) came calling. The feature Lights Out (2016) — Sandberg’s directorial debut — expanded the short into a story about family trauma wearing a monster’s face. Budget: $5 million. Gross: $148 million. Thirty-to-one. And here’s the detail that tells you who he was: it was the first time he’d ever been on a real film set. “I didn’t even know when to say ‘action,'” he’s said. “I had to ask somebody on set. My film school has been making Hollywood movies.”
Annabelle: Creation (2017) was the victory lap that became a coronation. The Conjuring Universe needed an origin story for its possessed doll; Sandberg delivered a period orphanage nightmare — $15 million budget, $306.5 million gross — widely considered the best of the Annabelle films and proof he could handle franchise machinery without losing the scares.
Then the pivot: Shazam! (2019), the DC superhero comedy about a kid who becomes a hero by saying a word. $373 million worldwide. The horror guy made the warmest superhero movie in years. Shazam! Fury of the Gods (2023) followed, and in 2025 he directed the film adaptation of the video game Until Dawn — back to horror, full circle.
What he actually did on the movies
On Lights Out, Sandberg did what the short did: he made darkness a character. The feature’s Diana — the entity that only moves in the dark — is a literalization of depression, of the thing in the family that everyone pretends isn’t there when the lights are on. The scares are built on the simplest possible mechanic (light on/light off), executed with total commitment. No-budget instincts, studio resources.
Annabelle: Creation is the franchise film as craft exercise. The doll could have been a prop; Sandberg made it a presence. The scarecrow sequence, the dumbwaiter, the staircase — set pieces built like clockwork, each one paying off. He treated a Conjuring spinoff like it was his own short film, and the box office rewarded him.
The cool information
“ponysmasher.” Say it out loud. One of the most successful horror directors alive built his career under a YouTube handle that sounds like a My Little Pony fan account. The anonymity was the point — no film school, no connections, just shorts good enough to travel.
The James Wan connection runs deeper than the Lights Out deal: Wan produced the feature, and Sandberg has cited him alongside The Exorcist, Alien, and Guillermo del Toro as influences. The student of commercial horror became its practitioner.
And that Irish Times interview remains the mission statement: “That was always my dream: to become a Hollywood director. But that’s something you can’t really talk about growing up in Sweden. If you said: I want to be a Hollywood director, people would say, yeah sure, be delusional.” He said it anyway. Then he did it. “I love making people laugh or making people scared.”
Signatures and habits
The simple mechanic, perfectly executed — darkness, a doll, a word. Light as a weapon and a metaphor. Family trauma in monster drag. The two-person crew ethic scaled up: even his blockbusters feel handmade. And Lotta Losten, always — wife, star, producer, the constant.
Why he matters
Sandberg is the proof of concept for the internet age: a kid with a camcorder and a YouTube account can scare Hollywood into calling. He didn’t just get the meeting — he got the franchise, the superhero film, the career. And he never lost the short-filmmaker’s discipline: one idea, executed relentlessly. From Jönköping to the Conjuring Universe to Shazam’s lightning — all because a woman turned off the lights.
