The Kane Parsons creation continues to benefit from strong word-of-mouth and repeat viewings. Chiwetel Ejioforβs central performance and the unsettling liminal aesthetic have clearly connected with audiences seeking original horror. At a $10M budget, the film has already crossed the 14x mark globally and stands as one of the standout micro-budget successes of the year.
Reality check: $7.5M on Day 10 gives a current 14.54x ratio. The Week 2 hold versus opening week remains the clearest signal of how far this phenomenon can run theatrically.
