Dance and Kamal go hand-in-hand. Now the actor is learning Kathak because the script of 'Viswaroopam' demands his character to know this dance form. The actor is getting his lessons in Delhi from none other than Kathak exponent Guruji Birjumaharaj, who is also responsible for choreographing Madhuri Dixit for a Kathak number in Sanjay Leela Bansali's 'Devdas.'
In 'Viswaroopam' there is a song sequence which requires Kamal's character to perform a Kathak number; hence around 50 dancers from Birjumaharaj's dance school are believed to have flown to Chennai to shoot the number. Another part of this song is touted to be shot from the US.
Music for this film is by hit Bollywood trio Shankar - Ehsaan - Loy. The film sees Kamal Haasan playing the lead role with Pooja Kumar playing the female lead. Andrea and Isha appear in important roles in this film. 'Viswaroopam' is touted to release in Tamil, Hindi and English as well.
