Backrooms Comes to HBO Max Friday: What to Know Before You Watch

Backrooms begins streaming on HBO Max on Friday, September 25. The date has been confirmed for the US and Spain. If you missed the A24 film in theaters, this is the first chance to watch it with a subscription in those markets. It is already available to rent or buy digitally, but a rental purchase is different from the HBO Max release.

The movie was directed by Kane Parsons, who first built the Backrooms idea through short videos online. The feature is not just a collection of those clips. It follows Clark, a furniture-store owner played by Chiwetel Ejiofor. A strange doorway opens in the basement of his store, and he enters a space of empty rooms and corridors that do not behave like a normal building. His therapist, Mary, played by Renate Reinsve, goes looking for him.

The film keeps the familiar yellow rooms from the original online idea, but it also spends time with Clark and Mary outside them. That makes the story easier to follow than a series of unexplained clips. It gives the actors room to react to the place, instead of relying only on the look of the rooms.

Do you need to watch the online videos first?

No. The film gives viewers its own characters and a clear reason for entering the strange space. Knowing Parsons’ earlier videos may make some images familiar, but the movie introduces Clark, Mary and the doorway for people who have never followed the online series. It keeps the main idea simple: an ordinary room can lead somewhere that is hard to leave.

The cast is a big part of the change from short videos to a feature film. Ejiofor and Reinsve give the audience people to follow through the rooms. Mark Duplass, Finn Bennett and Lukita Maxwell are also in the cast. The film started in US theaters on May 29, so this streaming date comes months after its cinema run.

Where can you watch it?

HBO Max starts carrying Backrooms on September 25 in the US and Spain. In the US, the film is also scheduled to air on the HBO channel on September 26. If you want to watch before Friday, A24 already lists digital viewing options for rental or purchase. Prices and stores vary by region, so check your local listing before paying.

The main thing to remember is that September 25 is the subscription-streaming date, not the film’s first-ever home release. If your country is outside the confirmed markets, do not assume the same service or date applies. Our Backrooms movie page has the cast and official images, and this article will be updated if the streaming plan changes.
