Nagarjuna's 'Om Namo Venkatesaya' will hit the screens on Feb 10th. In this interview, the experimental actor talks about how he approached the role of a Balaji devotee, his 100th movie, his sons' films and more.

'ONV' is an imaginative story-telling. How did you approach the role?

I totally relied on the vision of K Raghavendra Rao garu and JK Bharavi garu. The story starts when he is all of 8 years old and is told till he reaches 50. Unlike Annamacharyulu, who was a literary genius and was sophisticated, Baba's characterization is not on those lines.
