A making video of the Danga Danga song has been released by the makers. Featuring Ajith and Nayanthara, the song was one of the much-talked-about elements in the film. Incidentally, Danga Danga was also a chartbuster when it was released as a single just before the release of Viswasam. The song has been sung by the singing sensation, Senthil Ganesh and Rajalakshmi. D Imman has composed the music for the film. 

Also starring Nayanthara, Jagapathi Babu, Robo Shankar, Thambi Ramaiah amid others, Viswasam is Ajith’s fourth project with director Siva. The film locked horns with Rajinikanth’s Petta at the box office. The competition between the two films took an ugly turn as producers took potshots at each other raising a debate over the validity of box office numbers in Tamil cinema.
