Horror Shorts in Focus: Lights Out – The Two Minute Nightmare That Terrified the Internet
Before Lights Out haunted cinema screens, it was just a two minute homegrown experiment in fear, a tiny short film shot in a Swedish apartment that somehow scared its way around the world. No studio, no budget, and no reason to expect it would change a career. But that is exactly what it did for David F. Sandberg and his creative partner and wife Lotta Losten.
In 2013, the couple entered the UK “Who’s There?” Film Challenge with a short that played on one of humanity’s most ancient anxieties, the dark. The setup was deceptively simple, a woman turns off the lights, sees something move, turns them back on, and it vanishes. Off again, and the thing is closer. Two minutes later, you are questioning every shadow in your hallway and deeply regretting your electricity bill.
The film did not even win the competition. It quietly uploaded to Vimeo and YouTube, racking up a modest thousand views until the algorithm gods smiled. Within weeks, Lights Out went viral, racking up millions of plays and earning the kind of internet legend status usually reserved for jump scare prank videos and cats falling off tables. Horror fans could not get enough of its precision, no dialogue, no exposition, just a perfectly timed nightmare that leaves your brain begging for light.
And Hollywood noticed. Sandberg recalled that he and Losten suddenly found themselves flooded with emails from agents, producers, and studio executives. “I had to create a spreadsheet to keep track of everyone I had talked to,” he said. It was the kind of fairytale scenario every indie filmmaker dreams of, one short, one concept, and suddenly your inbox is on fire.
Soon enough, Sandberg found himself in Los Angeles with James Wan, who had just terrified the world with The Conjuring. Wan loved the short and offered to produce a feature version for New Line Cinema. The result, released in 2016, starred Teresa Palmer and Gabriel Bateman, expanding the original premise into a full story about a family haunted by an entity that could only exist in darkness.
For Sandberg, the transition from living room short to Hollywood set was eye opening. “Going from no budget to five million dollars felt like we could do anything we wanted,” he said, “but in Hollywood, five million is nothing.” He quickly discovered that while big productions have more toys, they also come with a lot of rules, including one about how many lightbulbs you can turn off.
The feature stayed true to what made the short so effective, clarity of concept and ruthless editing. Sandberg made sure the entity obeyed its own logic this time, explaining, “In the short, we did not care about breaking the rule of the creature not existing in light, but for the feature I felt that was very important.” The film went on to gross over 148 million dollars worldwide, proving that even the smallest idea can cast a very long shadow.
Lights Out’s success also launched Sandberg’s career. He went on to direct Annabelle: Creation and Shazam!, cementing himself as one of the few directors who can handle both demonic dolls and superheroes with equal confidence. And it all started with a two minute short made for fun on a quiet evening in Sweden.
Today, Lights Out is a textbook case study in viral horror, how the right combination of simplicity, timing, and primal fear can do more than just go viral. It can open doors to Hollywood, franchises, and a future where your next upload might be the one that changes everything.
So next time you switch off the lights before bed, think of Lights Out. Then maybe turn them back on again. Because if the internet taught us anything, it is that you never really know what is standing just out of view.
