Interestingly, it was for the Vignesh Shivan directorial Naanum Rowdy Dhaan that Nayanthara dubbed for the first time for herself.

Kaathuvaakula Rendu Kaadhal stars Vijay Sethupathi and Samantha as the other two leads. While Vijay Sethupathi's character is named Rambo, the characters played by Samantha and Nayanthara are named Khatija and Kanmani, respectively.

The film has music by Anirudh Ravichander while Vijay Kartik Kannan of Doctor fame serves as the cinematographer.

Speculations around the film's straight-to-streaming release are rife, but the makers are yet to announce whether the film will be opting for a direct OTT release or will hit the big screens.
