Music director Devi Sri Prasad is all smiles nowadays. Why? Because the composer has been asked by Kamal Haasan and ‘Oscar’ Ravichandran to do the background score for the most-awaited movie of the year, Dasavatharam. Devi Sri Prasad has previously composed for Vijay’s Sachin and Suriya’s Aaru in Tamil. Dasavatharam stars Kamal Haasan in 10 roles along with Asin and Bollywood glam queen Mallika Sherawat, who has an important role in the film. The music of Dasavatharam is by Bollywood’s Himesh Reshammiya. However, the makers were in search of a composer to do the BGM as Himesh was busy with his Hindi projects. They had initially approached music maestro A.R. Rahman, who was initially supposed to compose the music too. However, Rahman too was busy with prior commitments and politely declined the offer. Finally, the trio of Kamal Hasan, director K.S. Ravikumar and ‘Oscar’ Ravichandran zeroed in on the hotshot Tollywood composer to do the BGM and Devi Sri Prasad willingly accepted the offer. Devi Sri Prasad is also the composer of Kanthasamy, starring Vikram which the other most-awaited movie of 2008.
