The film is holding respectably through Week 2. The $3.3M figure shows clear audience interest in the viral horror concept and Chiwetel Ejiofor’s grounded lead performance. At a $10M budget, Backrooms has already delivered blockbuster-level returns and continues to benefit from strong word-of-mouth among genre fans.

Reality check: $3.3M on Day 11 gives a current 14.87x ratio. The hold percentage versus opening week remains the key signal for how high this micro-budget success can climb.
