Ace director Selvaraghavan's long-delayed Nenjam Marappathillai finally hit theatres last week, with the horror-thriller receiving an overall positive response from fans and critics. The film had sparked instant interest since the time of its announcement, but had witnessed a delay in its release for nearly four years, with fans continuing to discuss and delve deep about the plot, performances and other story elements on social media. A joint production venture of Escape Artists Motion Pictures, GLO Studios and Southside Studios, promotions for Nenjam Marappathillai starring SJ Suryah, Regina Cassandra and Nandita Swetha in the lead roles and featuring music by Yuvan Shankar Raja are still being carried forward actively, with the makers on Monday releasing the much-awaited 'Kannungala Chellangala' video song. 

Yuvan's songs in Nenjam Marappathillai have kept the film alive in the public's eyes all these years as the feedback to the music has been largely positive, with the composer also contributing for the vocals on the 'Kannungala Chellangala' track. Featured on SJ Suryah in a police station backdrop, the song became a hit along with the other tracks, with the director-actor's performance being a major highlight for fans. A subtle melody track, 'Kannungala Chellangala' is a step away from the other songs in the Nenjam Marappathillai album, which has once again seen a resurgence especially post the theatrical release of the film. The song's visuals also showcase SJ Suryah shaking his feet and the catchy steps have received a good response from fans of late. 

On the technical front, apart from Selvaraghavan serving as the director and the screenwriter and Yuvan for the music, Nenjam Marappathillai includes cinematography by Arvind Krishna and editing by GK Prasanna, for whom it was initially announced to be his debut in Tamil cinema. Selvaraghavan's fans are once again in a celebratory mood considering the filmmaker's previous release, NGK starring Suriya, Sai Pallavi and Rakul Preet Singh, received a mixed response in 2019.
