The concept of a "deadliest film" raises questions about the psychology of fear and the power of cinema to manipulate emotions. While "Antrum" may not be literally deadly, it undoubtedly taps into a deep-seated fear of the unknown, the unexplained, and the unsettling. The film's ability to evoke a visceral response can be attributed to its use of uncanny imagery, uncomfortable silences, and an overall sense of unease.
