What was announced at Cannes
Film Information's May 21, 2023 report records producer Kumar Mangat Pathak announcing that Panorama Studios and Korea's Anthology Studios would partner on a Korean-language remake of the Drishyam franchise. The announcement took place at the Indian Pavilion in Cannes. It concerned adapting a story for another language and market, rather than merely adding Korean subtitles to an existing film.

A partnership establishes an intention to develop a project. It does not on its own establish that principal photography has finished, that a distributor has scheduled screenings or that a particular actor has accepted a role. Company founders mentioned in a business announcement should not automatically be listed as the film's cast. Those later milestones need their own production or distribution confirmation. The linked Fighter timeline offers another example of why an announced date and an eventual theatrical release must be kept separate. This article preserves the Cannes 2023 development news without inventing a current Korean release schedule.
