Vijay Antony, the music director of 'Kadhalil Vizhunthen' has sung a song in the film. Vijay sang the song 'Kadavul Pataitha Azhagi' for the track. Later, director P.V. Prakash decided to have the song in Vijay’s voice, as he felt that the voice fitted perfectly to the tone of the song.

It is none other than the director himself who had written the song. Young lyricist Thamarai has penned the lyrics for the other songs.

'Kadhalil Vizhunthen' is an action-romantic set in the backdrop of a campus.

The film has Nakulan (Boys fame) and Sunena, a Telugu actress, as the lead pair. Sunena is making her debut in Tamil.

'Kadhalil Vizhunthen' is expected to be released on Pongal.
