Music composer Anirudh Ravichander has sung a song for Ai. The music has been composed by AR Rahman, whom Anirudh considers his mentor. Director Shankar was also present when the song was being recorded and is reportedly very happy with the result. Starring Vikram and Samantha Ruth Prabhu, the film is an intense action movie and has been made on a very grand scale. Filming is over and right now, the post production work is on.
