PICS: Went through 33 scripts before signing 'Shamitabh'

After 'Raanjhanaa', Dhanush waited for about eight months and went through some 33 scripts before 'Shamitabh' happened, which he feels is the toughest role in his career. "A lot of scripts came my way after 'Raanjhanaa'. I think I read about 33 scripts but there was nothing solid to back up my first Hindi film. I kept waiting for about eight months when R Balki called. He is like 'if you are free for a couple of hours do drop in'. After a two-hour narration I knew I was doing it," Dhanush said.
