The first Indian film to be shot in the Super 35 format.
All of the music, including the soundtrack and score, was composed in Thailand, where Yuvan Shankar Raja worked with the Chao Phraya Symphony Orchestra of Bangkok, which featured for the first time in a Tamil film.
Kamal Hassan rendered his voice for a song even though he didn't act in the film.
Due to its Classic/Cult Status, the movie was re-released almost ten years after the release on 27th November 2016 at GK Cinemas, Porur, Chennai with the same festive spirit and celebrations by its Fans, like a new release and ran in full house.
After the release of 'Pattiyal' whose theme was the same as 'Pudupettai' (dwelling on gangsters in Chennai), Selvaraghavan wanted to re-do many of the scenes to make them look fresh and new, hence the release of this movie had to be delayed.
