Tamil star Vijay Sethupathi on 15 September 2026 released the official teaser of Mandavetti, a supernatural crime thriller directed by Saranraj Senthilkumar and headlined by actress Komalee Prasad. The two-minute teaser plunges viewers into a world where dread arrives without logic and the boundary between the known and the unknown steadily dissolves.

How the teaser unfolded

Sethupathi shared the teaser on his X (formerly Twitter) timeline with the caption: 'Here is the official teaser of #Mandavetti.' The clip opens with a woman in a trance-like state whose presence immediately triggers a creeping, inexplicable sense of unease. From that point, the narrative unfolds through fragmented conversations, half-glimpsed characters, and scenes of ordinary people confronting something entirely beyond their grasp.

At the heart of the mystery is an enigmatic force known as 'Senji Saamy' — a presence that appears to be directly linked to the unsettling events cascading through the story. Crucially, the teaser resists easy answers: every hint of revelation is engineered to leave audiences with a deeper, more disturbing question.

Komalee Prasad's role and transformation

The teaser positions Komalee Prasad as the emotional anchor of the film's supernatural world. According to the promotional material, her character embodies vulnerability, rage, suffering and mysticism in equal measure — a combination that reportedly required an intense physical and psychological transformation. Her performance gives the unsettling mythology a recognisably human centre, which the filmmakers appear to be banking on as the film's primary emotional hook.

Story, mythology and the 'Senji' universe

Mandavetti has been conceived, according to sources, as a dark supernatural crime thriller that blends psychological tension, regional folklore and raw human emotion. The film draws on the mythology surrounding 'Senji', described as a fierce local deity whose presence drives the narrative into deeply charged, morally ambiguous territory. Written, directed and produced by Saranraj Senthilkumar under the banner of Tuskers Den Pictures, the project represents an ambitious foray into South Indian folklore horror.

Full technical crew

The film's technical team includes Prakash Manithan as cinematographer, Guna Palinisamy as editor, and Deepak Venugopal as music director. Gowtham has choreographed the stunts, Sangeetha Sen is the costume designer, Tony J is handling sound mixing, Balaganghadaran is overseeing DI grading, and Vijayan is responsible for VFX.

With the teaser now out, audience and trade attention will turn to a release date announcement — and whether Mandavetti can carve a distinct space in Tamil cinema's increasingly crowded supernatural genre.
