Thamizh or "Thamillh" is a 2002 Indian Tamil-language action drama film directed by Hari, in his directorial debut, and produced by Amudha Durairaj under Deivanai Movies.

The film stars Prashanth and Simran, alongside Vadivelu, Urvashi, Nassar, Ashish Vidyarthi and J. Livingston.

[2] Simran was selected as heroine pairing with Prashanth, for fourth time after successful collaborations in Kannedhirey Thondrinal (1998), Jodi (1999) and Parthen Rasithen (2000).

[4] The team had worked on pre-production for close to a year and the script was ready prior to the start of the shoot, with Hari revealing he was inspired by the 1989 Malayalam film Kireedam.

[6] Prashanth had performed a lengthy dialogue in front of Madurai Meenakshi Temple which gained accolades from the onlookers.

The similarities of title and release date between Thamizh and the unrelated Thamizhan created confusion with the producers of both films unable to accommodate any changes.

[4] Malathi Rangarajan of The Hindu noted "Thamizh is backed by a strong storyline and a significant end [sic] and the positive twist is appealing.

"[9] Malini Mannath of Chennai Online wrote, "Debutant director Hari reveals commendable confidence, in his very first venture, crafting his screenplay intelligently, with well defined characters, engaging incidents & a racy narrative style.
