The movie 'Backrooms' earns $38 million on opening day…success after YouTube

"The Backrooms" opened to $38 million on day one, putting it on track for as much as $90 million over the weekend.

That would top A24’s previous opening record and even exceed "The Mandalorian and Grogu"’s first-day haul.

Made for about $10 million, the low-budget horror film is drawing strong reviews and box-office attention.

The result underscores how a YouTube-born creator like Kane Parsons can break through in theaters.
