With actor Aadhi and director Arivazhagan reuniting after over a decade in Sabdham that was released recently. The duo first was a part of Arivazhagan's debut Eeram, which was also a horror drama.

Arivazhagan was praised by his mentor and legendary filmmaker Shankar for his work in Sabdham. He called the incorporation of sound in a horror film a "new approach." He went on to add that Arivazhagan's technical strengths and engaging storytelling are noteworthy. Shankar also praised sound engineer Udaykumar, actor Aadhi, and music composer Thaman, calling their work impactful.

An excerpt from the CE review of the film reads, "Sabdham, for all its technical brilliance, makes the cardinal sin of the horror genre by failing to deliver a single thrilling moment. Moreover, the desperation is palpable with red herring jump scares, and it is almost always something predictable like a prank or a video game pause screen. Such attempts reveal the filmmaker’s lack of confidence in the story, and that is unfortunately transmitted to the audience as well. The story clearly does not deserve such disrespect, as it is ripe with several interesting ideas."

Sabdham stars Aadhi as a paranormal investigator and Lakshmi Menon as a doctor who delves into a chilling sequence of events. Simran, Laila, Redin Kingsley, MS Bhaskar, Rajiv Menon, Vivek Prasanna, and TSR Srinivasan also star in the movie.

The technical team consists of Thaman composing music and lyrics written by Viveka, Arun Bathmanabhan as the director of photography, Sabu Joseph VJ doing the editing, Manoj Kumar as the art director, and Stunner Sam handling the stunt department.
