The film is showing typical Week 3 moderation but is still adding respectable numbers. The $3.3M figure on Day 17 reflects continued interest from core audiences. The filmโs unique concept based on internet lore has helped it stand out and maintain better longevity than many horror releases.
Market-wise, the performance remains strongest among younger audiences familiar with the original web series. The film has benefited from strong social media engagement and positive word-of-mouth.
With a current 17.01x ratio, Backrooms has already achieved BLOCKBUSTER status. It continues to be one of the most profitable releases of the year relative to its budget.
