The genre’s roots in Hindi cinema can be traced back to the 1960s, when directors experimented with noir aesthetics and complex characters. Films like "Koi... Mil Gaya" (1961) introduced subtle psychological tension, setting a foundation for future explorations. Though not overtly labeled as thrillers, these early works laid the groundwork for a genre that would flourish decades later.
Fast forward to the 2000s, and a new wave of filmmakers began to embrace darker themes and intricate narratives. The turn of the millennium marked a pivotal era where psychological depth became a commercial asset, ushering in a renaissance of suspense that resonated with a broader audience.
