Vadivelu, who once ruled the roost in Tamil cinema, has been taking things slow for the past decade. He was last seen in Vijay's Mersal in 2017. Now, after a gap of about four years, Vadivelu is returning to acting. He will play the lead in a film titled Naai Sekar. 

A source close to the project confirms that Naai Sekar, directed by Suraj, is a spin-off of his 2006 crime drama Thalai Nagaram. Naai Shekar was the name of Vadivelu's character in the film, a comic self-proclaimed don. The upcoming film will feature the character in a different setting and story. 

Naai Sekar will mark the fourth collaboration of Vadivelu and Suraj. In addition to Thalai Nagaram, the two have worked together in Marudhamalai and Kaththi Sandai. 

Details of the cast and crew of the upcoming film are still under wraps. The makers are planning to start the shoot in April and are expected to officially launch the film on Tamil New Year's day (April 14).
