Weekend Box Office May 29-31, 2026: Backrooms Dominates with $81.5M Record Opening

A24’s Backrooms delivered a massive, record-breaking debut to claim the top spot at the domestic box office this Memorial Day weekend, stunning with an estimated $81.5 million opening. The horror hit led a competitive frame where several holdovers showed strong legs and a new family comedy entered the mix.

Here’s the top 5 breakdown:

1. Backrooms (A24) – $81.5M (New) | Total: $81.5M

A24’s biggest opening ever comes courtesy of Kane Parsons’ (Kane Pixels) feature directorial debut, adapting his viral YouTube horror series. The film follows a therapist (Renate Reinsve) whose patient (Chiwetel Ejiofor) vanishes through a mysterious doorway in a furniture store basement, leading her into an endless, nightmarish maze of liminal spaces. Part psychological horror, part existential creepfest, Backrooms has been praised for its atmospheric tension and clever blend of internet lore with high-concept storytelling.

2. Obsession (Focus Features) – $26.4M (-10% from last weekend estimate) | Total: ~$105M

This twisted romantic horror continued its impressive run, actually growing in its third weekend. Directed by Curry Barker, the film stars Michael Johnston as a shy guy who uses a supernatural “One Wish Willow” to make his crush (Inde Navarrette) love him obsessively — with terrifying, deadly consequences. Audiences are loving the dark, cautionary tale about desire and codependency.

3. Star Wars: The Mandalorian and Grogu (Disney) – $25M (-69%) | Total: ~$137M

Jon Favreau’s big-screen Mandalorian adventure starring Pedro Pascal and Grogu dropped sharply in its second weekend but remains a solid performer. The film follows the fan-favorite duo on a new galactic journey filled with action, heart, and plenty of Star Wars lore.

4. Michael (Lionsgate) – $11.7M | Total: ~$340M

Antoine Fuqua’s Michael Jackson biopic, starring Jaafar Jackson, continues its impressive long run in its sixth weekend. The film chronicles the King of Pop’s rise from the Jackson 5 through his groundbreaking artistry.

5. The Breadwinner (Sony) – $7.5M (New)

Nate Bargatze’s feature film debut as a hapless car salesman trying to hold down the fort with three kids while his wife pursues a big opportunity. This PG family comedy brings wholesome laughs and relatable dad humor to theaters.
