Brace yourself, gamers! The smash-hit horror movie phenomenon, Backrooms, directed by the prodigious 21-year-old Kane Parsons, is storming onto your screens in a spine-tingling spectacle. Mark your calendars for Friday, September 25th, when Backrooms makes its grand debut on HBO Max. The following day, it'll also grace the small screen on HBO linear channels at 8pm ET. With a staggering $400 million gross worldwide and becoming A24’s highest-grossing movie ever, Backrooms has left audiences clamoring for more. This cinematic terror-fest initially hit theaters back in May, dominating box offices and earning an 87% rating on Rotten Tomatoes. As its theater run came to a close, extended "Everything Must Go" screenings became available, featuring over 15 minutes of additional footage inspired by Parsons' original YouTube series. Although this extra content can currently be viewed for free on YouTube, it remains unclear whether it will find its way onto HBO Max. For those eager to catch the movie at home before its HBO premiere, Backrooms is available for digital rental or purchase on platforms like Prime Video, and 4K Blu-rays loaded with over three hours of special features are also up for grabs from the A24 Shop. With whispers of a potential sequel in the air and more creepypasta-inspired movies getting the green light following Backrooms' success, this is one movie you won’t want to miss! Blythe, our Audience Development Coordinator at IGN, can't wait to dive back into this terrifying cinematic labyrinth.
