Trivia

  • The film's working title was 'The Upstairs Sound', referencing the central auditory mystery.
  • Director Shrikanth Senj insisted on using only practical lighting from lamps and flashlights within the apartment set.
  • The recurring thumping sound was created by a custom device that dropped a sandbag onto a hollow wooden platform.
  • Lead actor Aditya (playing the journalist) stayed alone in the set apartment for 48 hours before filming to induce isolation.
  • The screenplay was partially inspired by a real, unsolved case of mysterious noises reported in a Chennai housing board building in the 1990s.
  • The film's tight 14-day shooting schedule was a deliberate choice to maintain a high-pressure atmosphere for the cast and crew.
  • A single, continuous 7-minute shot in the climax required 32 takes to achieve the desired emotional breakdown.
