For quite some time, Hollywood has moaned about the lost YouTube generation at the box office: How do we get the Gen Z set in? Sure, they’ll show up for a Marvel movie, but today’s 18-25 demo aren’t attending like they did in the 1980s.

Finally, arguably this year, Hollywood has been able to harness that crowd, making content that they’ve always wanted, to get them out of the house. A24‘s record opening of Kane Parsons pic Backrooms ($81.4M domestic, $118M) is the pinnacle of that in a year that kicked off with YouTube star Markiplier’s self-distributed feature take of indie videogame Iron Lung ($17.8M opening, $40.8M domestic, $50M WW) and then ratcheted up with Focus Features’ $15M+ acquisition, Curry Barker’s Obsession which outstripped its $8M-$9M projected domestic opening for a $17.1M start, and surged in its Memorial Day and post-holiday weekends to become Focus Features’ highest grossing movie stateside with $104.7M, and one of their highest grossing with $148M. Also Parsons at 20 is the youngest filmmaker to open a movie at No. 1 with a huge haul.

In a way, you could say that when it came to dynamiting Gen Z, props should be given to last year’s near billion grossing sensation from Warner Bros and Legendary, A Minecraft Movie, however, that was a piece of epic Microsoft IP much in the vein of a Super Mario Bros. Backrooms, Obsession and Iron Lung are all thrifty priced indie titles with shoestring marketing budgets.

There were previous attempts made to harness the YouTube crowd. Remember Austin-based RoosterTeeth which was eventually purchased by Warner Bros? They struck lightning with a heavily watched web series Red vs. Blue in 2003 which led to their first $2.4M crowdfunded 2015 action comedy feature Lazer Team. But it didn’t have the marketing and distribution umpf of a major studio, only grossing $1.1M at the domestic B.O. in a limited release. RoosterTeeth was shuttered by the David Zaslav -run Warner Bros Discovery due to “monetization shifts, platform algorithms, advertising challenges, and the ebb and flow of patronage—all these converging factors have led to many closures in the industry,” per the division’s general manager Jordan Levin in a memo to staff in March 2024.

While Backrooms and Obsession arguably make a sweet double-feature this weekend, the two couldn’t be more different. Obsession is an original horror movie from Barker; however, he’s nurtured his previous films on YouTube. Backrooms is a powerful digital rabbit hole IP, and A24, in their marketing campaign, spoke to those deep backrooms of fans in Reddit (more on that further down).

To say that nobody saw Backrooms coming isn’t true. Early summer tracking indicated there was a fever brewing. We just didn’t know how big it would be. Three-week tracking indicated a $20M start at least. Prognosticating north of that seemed daredevil as the only comp at that time was Iron Lung, and the YouTube generation can be fickle and fierce (they were quite hard on Backrooms with a B- CinemaScore).

Petaluma, CA native Parsons didn’t create the early iterations of Backrooms. The urban legend (aka internet-born horror creepypasta) where victims became trapped in endless mazes, yellow-wallpapered office rooms, damp carpets and buzzing fluorescent lights, was first created in 2019 on 4chan. I’m told that an anonymous creator began it, but the IP resides in a creative expression sector of the law which loopholes its way out of any copyright ownership as fans have morphed the concept into their own interpretations on Reddit, fan wikis, indie games on Roblox and Minecraft. Enter Parsons, aka Kane Pixels, who became the face of this digital craze using Blender, Unreal Engine and found footage to create The Backrooms: Found Footage, which racked up (revised) 224 million views across 22 videos.

In early 2022, several producers started chasing Parson’s Backrooms shorts. 3 Arts manager Will Rowbotham and Luke Maxwell signed the then 17-year-old. Both helped Parsons shape Backrooms into feature film format. 3 Arts facilitated the process in securing rights to Parsons’ take on internet IP. The two companies shoring up huge interest were James Wan’s Atomic Monster (whose Michael Clear led the charge) and Shawn Levy’s 21 Laps (whose then Dan Cohen took lead). Clear and Cohen were amigos, and rather than compete, linked arms on Backrooms and won the producer bakeoff. Atomic Monster and 21 Laps had already teamed on Netflix’s There’s Someone Inside Your House and MGM/Amazon’s Seasons.

Atomic Monster and 21 Laps brought the project to Chernin Entertainment to finance, that company already having a deal with A24. The Everything Everywhere All at Once multi-Oscar-winning studio, natch, had a rabid passion for the project. “They’re messaging from the beginning was to lean into the weird,” Clear tells Deadline.

Why was the movie made for under net $10M? Parsons was a first-time filmmaker, not to mention, there was an enormous upside for everyone to keep overhead low. For Chernin, there’s an inverse relationship between budget and taking risks. Chris Ferguson’s Odd Fellows were brought on as producers for the 30-day Vancouver, Canada shoot. He’s known for delivering high quality fare at a low cost, read Oz Perkins’ Longlegs and The Monkey. Perkins himself came aboard as a day-to-day mentor to the 19-year-old Parsons. 12 Years a Slave Best Actor Oscar nominee Chiwetel Ejiofor was prime to play the protag of a guy trapped in an adjacent spooky universe to his banal strip mall furniture store. For the producers, he exhibited ferociousness and extreme vulnerability. Pre-her Sentimental Value Oscar-nominated explosion, Renate Reinsve was ideal to play the therapist who tries to save him, the actress having a knack for being stoic yet with a tempest underneath.

The P&A spend for Backrooms is around, though higher than the $10M spent by NEON on Longlegs. A24 embraced the ‘For us, By us’ mentality of Backrooms. Instead of massive outdoor buys and TV spots, they built a campaign designed to live where Gen Z already lives, read YouTube, TikTok and Reddit. The distrib’s angle in the campaign was to speak the language of the communities that have been building the Backrooms mythology for years on those platforms. The insight was that this audience didn’t need to be reached, rather it was essential to meet them. They’ve been living with this original IP for years, creating content, developing lore and organizing community around it. A24’s job wasn’t to introduce them to something new and to show up authentically inside something they already owned. That authenticity is what made the marketing materials go viral. When content resonates with something already alive in culture, the community does the distribution.

Case in point, when it came to an outdoor campaign, A24 bought a billboard in Oshkosh, WI, the original location of Backrooms and one in NYC (East Broadway mall, which again is lore in the IP). All of this went wild on social.

The trailer became A24’s most viewed trailer at 24 hours (and seven days) from launch, largely driven by YouTube and TikTok. Parsons went down to Brazil’s Comic-Con where A24 launched Easter eggs for fans including an in-world flyer for ‘Cap’n Clark’s Ottoman Empire’ and fax number for fans to submit to with more to come. There was also an in-world commercial that dropped a month ago on Reddit.

Ahead of opening weekend, social media analytics firm RelishMix weighed the social media universe for the pic across TikTok, YouTube, Instagram, X and Facebook at 220M, 48% ahead of original horror norms.

RelishMix reported that there was enormous positive buzz ahead of opening with “audiences treating the film less like a studio release and more like the culmination of a long-running internet phenomenon. The strongest theme is admiration for creator Kane Pixels (Parsons) with many viewers expressing disbelief that such a polished theatrical experience came from a filmmaker barely out of his teens. Fans repeatedly praise the world-building, analog texture, tension and commitment to preserving the eerie DNA of the original shorts while expanding the mythology. The chatter also reflects strong theatrical enthusiasm, with ticket purchases, opening-night attendance and sequel requests appearing throughout the discussion. Comparisons work in the film’s favor, positioning Backrooms alongside Iron Lung and cult horror touchstones rather than disposable genre fare. Sentiment is reinforced by reactions such as ‘Amazing world-building and the tension was so good’ and ‘I haven’t been this unnerved watching a film since I was too young to watch horror.’ Similar enthusiasm appears in comments like ‘It’s like the Blair Witch Project but inside an abandoned Sears’ and ‘love that it still has the feeling of the original found footage and yet is different and unique.'”

A24 also had a public experience ‘Enter the Backrooms’ with a DJ set by Instupendo, livestreamed on YouTube May 13–17. The waitlist filled within 15 minutes of posting and hundreds came through including creators. 

McDonalds even got in on the fun, making their own Backrooms version on X.

A UCLA Gen Z Teens & Screens report found that nearly 80% of its respondents sometimes, most of the time, or always watch TV shows and movies on YouTube or TikTok rather than on TV or in theaters. Meanwhile, an Oglivy New Gen Z study found that 92% of 18-25 year olds trust recommendations from influencers more than traditional advertisements or celebrity endorsements. At the same time, 83% of Gen Z fans say they know their engagement shapes how creators and brands develop content — fandoms are participatory, meaning influence is bidirectional. What Markiplier, Barker and now Parson have proven is that when they offer their faithful a big screen event, they’ll come. Industry sources also believe that Gen Z’s lockdown during Covid has also spurred them to step away from their devices and head to cinemas as an oasis.

So when it comes to crying about the lost YouTube generation at the box office, it sounds like the town can stop worrying.

“You can’t say that this demographic doesn’t want to be entertained or go to the movies,” Backrooms producer Peter Chernin tells Deadline, “We have an obligation to figure out how to attract this audience. Giving up would be futile.”
