The trailer of Sarathkumar's upcoming film The Smile Man was released by the makers on Monday. The film is directed by Syam-Praveen and is slated to release in theatres on December 27.

The film stars Sarathkumar as Chidambaram Nedumaaran, a police officer with Alzheimer's who is tasked with finding a copycat killer. The assassin leaves his victims in various places, such as under a bridge, in a field, and on top of a tree, with their mouths mutilated and stitched in a way that resembles a smile. The trailer also reveals that the killer resurfaces everytime Sarathkumar comes out in the light, and his primary target is Chidambaram himself. The screenplay is written by Kamala Alchemis.

In an earlier conversation, Syam said, "The Smile Man is a crime thriller starring Sarath sir in the role of a retired police officer with early signs of Alzheimer's. With a serial killer on the run, the character has to crack the case before he loses his memory."

The cast also includes Sija Rose, Ineya, George Maryan, Suresh Menon, Kumar Natarajan, and Aazhiya.

The film's technical team includes filmmaker Vikram Mohan, composer Gavaskar Avinash, and editor San Lokesh. Salil Das, Anish Haridasan, and Anandan T produced the film.
