The Backrooms box office just rewrote the rules this Memorial Day weekend. Kane Parsons’ $10 million A24 horror film — adapted from his own viral YouTube series — blasted out of the gate with $81.4 million domestically and roughly $118 million worldwide. That’s not just the biggest opening in A24’s 14-year history. It’s the kind of debut that makes studio executives sit up and take notice of what a 20-year-old director with a camera and a creepy idea can actually do.
Theaters were packed. Phones lit up the dark rooms. And the numbers kept climbing through Sunday. By the final tally, Backrooms had claimed the top spot and left almost everyone else scrambling.
How a YouTube Sensation Became a Box Office Monster
Parsons turned the internet’s favorite liminal nightmare into a feature that felt both familiar and brand new. The film stars Renate Reinsve and Chiwetel Ejiofor and traps audiences in those endless yellow hallways where fluorescent lights hum and dread builds with every wrong turn. Word spread fast among the same Gen Z crowd that made the original videos blow up. Roughly 88 percent of the audience was under 35, and more than half showed up specifically because they already knew the Backrooms lore.
You could feel it in the lobbies. People weren’t just watching — they were reacting out loud, sometimes too loud. A few theaters even fielded complaints about fans narrating the tension on screen. That’s the kind of engagement money can’t buy. The $10 million budget is already looking like one of the smartest investments of the year.
Obsession Keeps Pulling Off the Impossible
While new releases fought for attention, Focus Features’ low-budget horror sleeper Obsession delivered yet another jaw-dropping performance. The film added another $26.4 million this frame — a 10 percent jump from the prior weekend — pushing its domestic total past $104.7 million. That’s right: a movie made for under $1 million is now one of the most profitable releases of 2026.
Horror almost never climbs in its third weekend, especially not after Memorial Day. Obsession has done it twice. Audiences keep talking about it, keep dragging friends, and the movie just refuses to die. It’s the kind of word-of-mouth run that turns a quiet little thriller into a genuine phenomenon.
Mandalorian & Grogu Takes a Painful 70% Hit in Week Two
Star Wars fans felt the sting this weekend. The Mandalorian and Grogu opened to a solid $81.7 million three-day debut over Memorial Day, but the follow-up frame delivered a classic sophomore slump — a steep 70 percent drop that left it hovering around $24–25 million. The four-day opening had looked promising at nearly $100 million domestically and $167 million worldwide, but the shine faded fast once fresh competition arrived.
Some critics called the movie an extended TV episode. Audiences gave it stronger marks (A- CinemaScore, 88–89 percent positive), yet the drop tells the real story. In a weekend where a brand-new horror property from a 20-year-old creator felt electric, even Baby Yoda couldn’t hold the same gravitational pull he once did on Disney+.
This Weekend’s Box Office Snapshot
| Rank | Movie | Weekend Gross | Change | Cumulative (Domestic) |
|---|---|---|---|---|
| 1 | Backrooms (A24) | $81.4M | New | $81.4M |
| 2 | Obsession (Focus Features) | $26.4M | +10% | $104.7M |
| 3 | The Mandalorian and Grogu (Lucasfilm) | ~$24.5M | -70% | ~$137M+ |
What This Weekend Really Means
Three stories collided and told us something important about where audiences are right now. Original ideas with authentic voices — even ones born on YouTube — can still crush it when the marketing, timing, and cultural moment line up. Low-budget horror with genuine word-of-mouth can outrun big-studio expectations for weeks. And even the mightiest franchises feel the heat when something fresher and scarier drops at exactly the right time.
Backrooms didn’t just win the weekend. It announced that the next generation of filmmakers is already here and ready to scare the hell out of us — profitably.
The Mandalorian and Grogu will regroup. Obsession will keep surprising everyone. But this weekend belonged to a kid from the internet who turned an endless hallway into an $81 million opening. That’s the kind of story Hollywood can’t ignore.
