Recently, a release date was announced for Karthi's 27th film, Vaa Vaathiyaar. The Nalan Kumarasamy directorial, also starring Krithi Shetty, is set to open in theatres on December 5. In a recent interview with Cinema Vikatan, the director revealed key details about the plot of the upcoming film.

He said, "I wanted to make a proper action masala film, like the ones we used to get in the 80s and 90s. The story revolves around an MGR fan who believes his grandson shares a special connection with MGR. As time passes, the boy grows up to become Ramu (Karthi), a fun-loving, easygoing police officer. He forms a close friendship, but certain unexpected events put his grandfather’s life in danger. The film is about how Ramu transforms after that turning point.”

Apart from Karthi and Krithi Shetty, the film also stars Sathyaraj, Rajkiran, Anandaraj, Shilpa Manjunath, Karunakaran, GM Sundar, Vadivukarasi, and Madhur Mittal, among others.

The previously released teaser of Vaa Vaathiyaar had scenes of Karthi's character, who takes charge as a cop, shown to be flamboyant and accorded a grand welcome. What follows is Santhosh Narayanan's background score and an in-sync character reveal. Recently, the team also unveiled the first single, titled 'Uyir Pathikaama'. The song is sung by Vijaynarain, Aditya Ravindran, and Santhosh Narayanan, with lyrics written by Vivek.

Vaa Vaathiyaar has music by Santhosh Narayanan in his third collaboration with Kumarasamy after Soodhu Kavvum (2013) and Kadhalum Kadandhu Pogum (2016). The rest of the technical team includes cinematographer George C Williams and editor Vetri Krishnan. The film is bankrolled by KE Gnanavel Raja under his banner, Studio Green Productions.
