In the song "Vaarayo", you can hear Aishwarya Rai calling her grandmother "Miss World". Aishwarya Rai came into the world of movies after she became Miss World in 1994.
Originally the song "Anbe Anbe" was recorded with less percussion than what it has now. A R Rahman, who composed the song, gave it to director Shankar for picturisation. After seeing the visuals of the song, Rahman decided to add more sound effects to the song to make it rich.
