Kanimozhi is a 2010 Indian Tamil language musical romance film directed and written by Sripathi Rangasamy and jointly produced by T. Siva and Sona Heiden.

Subsequently, posters emerged around Chennai without any credits attached, only featuring the bold lettering of the film's name to create hype.

[3] Swati Reddy, who featured opposite Jai in the 2008 blockbuster, Subramaniyapuram, was initially considered for the leading female role but was then dropped.

Shazahn Padamsee, who had appeared opposite Ranbir Kapoor in Rocket Singh: Salesman of the Year, subsequently signed on and made her début in Tamil films.

The event was attended by prominent directors including Bala, K. S. Ravikumar and Venkat Prabhu, and several cast members from Jai's previous film, Chennai 600028.

[15] Despite being a love story, the lead pair had only shot together for two weeks, although they have since stated that they bonded during the filming, helping the on-screen chemistry of the characters.

[22] An animated trailer, the first of its kind in Indian cinema, featuring lead actors Jai and Shazahn Padamsee was screened with three songs from the film.

The producers held a premiere for Kanimozhi on 25 November 2010 at Sathyam Cinemas, Chennai for special invitees including Silambarasan, Prasanna and most of Jai's co-stars from his previous films.

Kanimozhi took an average opening at the Chennai box office, beginning in third position and completing 116 shows over the weekend, grossing 14 lakh rupees.

[27] Jai's role was appreciated and described as "endearingly likeable", while Shazahn Padamsee "looked pretty and was photographed well" but "could have invested more energy and expression to her character".

[28] Sripathy is praised, citing that "the debutant filmmaker’s portrayal of characters is appealing" but that "the film fails to offer grippingness at several points".

[28] The performances from the actors received a mixed response with Jai dubbed as "too raw and naturalistic" and Shazahn Padamsee being likened to a "Barbie Doll without reaction".

[29] The Hindu newspaper gave it a more critical review, with a verdict that the film is "a real test of your patience" but revealed it was a "genuine attempt at creating realistic cinema that also entertains", praising the story and the screenplay.

[31] It cites that for Jai "it is just another film in his career" as per for Vijay Vasanth,[31] while Shazahn Padamsee's performance is particularly criticised with a claim that she "does not seem to know the spelling of emotion in any scene".

She claimed that she entered into an agreement with T. Siva, proprietor of Amma Creations, on 28 January 2010, for purchasing the entire rights to Kanimozhi and thus secured 50% for any subsequent dubbed versions.

Heiden said that Siva had entered into an agreement with third parties for dubbing the film in Telugu, alleging that he forged her signature and sold the rights.
