The film stars Kishore and Dhruvva in the lead roles while Mrudhula Bhaskar, Anumol and Ram among others form an ensemble cast.

Perumal Pillai revealed that the film was based on a real-life incident from the 1990s, which revolved around two opposition clans in South Tamil Nadu.

The film was predominantly shot around Tirunelveli, while the team also managed to feature a Dussehra festival live in Thiruchendur, as a part of the script.

The film opened in March 2015 to mixed reviews, with a critic from Sify.com stating "what prevent Thilagar from being a classic is the unwanted romantic track, loud melodrama and abrupt ending", giving it an "average" verdict.

[7] Behindwoods.com also gave the film a middling review, adding "overall, Thilagar is a seen before, heard before story, supported by good performances from Kishore and Dhruwa".
