Psychological thrillers in Indian cinema prioritize the mental and emotional states of characters over physical action or external conflict. These films typically employ unreliable narrators, carefully paced suspense, and significant plot twists to challenge the viewer's perception of reality. Unlike standard procedurals, the focus remains on the subjective experience of the protagonist or antagonist, often blurring the line between sanity and delusion.
While predominantly associated with Bollywood, the genre has seen significant growth in Tamil, Malayalam, and Telugu cinema. This regional expansion has introduced a wider variety of storytelling techniques, including non-linear timelines, surrealist visual cues, and a deeper integration of local folklore or social pressures into the psychological framework. Fresh Pages notes that this diversity has elevated the genre from simple suspense to complex social commentary.
