After unveiling Arulnithi's first poster from Demonte Colony 3, director Ajay Gnanamuthu has now released Priya Bhavani Shankar's look from the horror thriller. Similar to Arulnithi's character, her role too seems to be teetering on the edge of evil. She looks pregnant and has blood on her hand and stomach. Sharing the eerie look, the makers wrote, "When darkness comes to rule, evil takes over."

While the second part had the tagline, 'Vengeance of the Unholy', the third part is titled 'The End is too far,' suggesting that the murky side behind unknown evil incidents will continue to thrive amidst attempts to thwart it.

Demonte Colony 2 was released in 2024 and continued the story of Arulnithi where he played dual roles. As earlier reported, the third part's returning cast also features lead actors Archana Ravichandran, Muthukumar and Meenakshi Govindarajan. Sam CS returns as the music composer for Demonte Colony 3.

While plot details for the third part remains unknown, the film will release during the summer of this year.

The other members of the technical team include cinematography by Sivakumar Vijayan, editing by Kumaresh D, and dialogues by Pattukkottai Prabakar. The film is produced by Sudhan Sundaram, Manish Singhal and Durgaram Choudhary. RC Rajkumar, Akshat Singhal and Mohit Singhal serve as co-producers.

Speaking about the new film during the original film's tenth anniversary in May 2025, the director took to his X handle and wrote that they are working hard to craft a "chilling, cinematic and unforgettable theatrical experience" for the third part.
