The horror film "Backrooms," produced by A24 and Atomic Monster, is projected to earn approximately $20 million [1] during its opening weekend.
This projection suggests the film could become a surprise hit during the competitive summer movie season. High opening numbers for a horror title in late May often indicate strong organic interest and potential for longevity in the domestic market.
The movie is scheduled to debut in the U.S. from May 29 to May 31, 2026 [1], coinciding with the post-Memorial Day weekend. Analysts said the current tracking is impressive for the project, noting that the film is positioned to potentially exceed initial expectations [2].
Industry data indicates the $20 million [1] estimate serves as a baseline for the opening window. Because the film is arriving during a period typically dominated by major studio blockbusters, a strong start would signal a significant appetite for the specific style of horror presented in "Backrooms" [3].
While the film faces a crowded summer slate, the partnership between A24 and Atomic Monster has historically targeted niche audiences that drive high per-screen averages. The current tracking suggests that "Backrooms" may capture a broader audience than typical indie horror releases, positioning it as a standout performer for the late May window [2].
“The horror film "Backrooms" is projected to earn approximately $20 million during its opening weekend.”
A $20 million opening for a non-franchise horror film during the summer peak indicates a strong transition of internet-born lore into commercial cinematic success. If the film maintains this momentum, it validates A24's strategy of leveraging digital trends to secure mainstream box office returns against larger studio competition.
