Produced by Subaskaran under the banner of Lyca Productions, Sigma stars Sundeep Kishan and Faria Abdullah in lead roles, with music scored by Thaman and cinematography by Krishnan Vasant. Following its First Day First Show (FDFS) screenings at Kumaran Cinemas and across theaters, social media platforms were flooded with contrasting audience evaluations. While a section of viewers praised the film as a full-throttle "mass entertainer" highlighting Sundeep Kishan's screen presence, high-octane action sequences, and engaging interval setups, critics and netizens noted that the screenplay and character development lacked depth, terming the narrative structure formulaic for a debut project. The premiere saw emotional moments as Jason Sanjay’s family attended in support, with fan chatter noting the symbolic blessing of his father Thalapathy Vijay, who continues his public duties as a political leader and Chief Minister candidate.
