Asked why he was doing unconventional roles in Bollywood as opposed to his larger-than-life roles down in southern cinema, Dhanush said: "I have been trying to mix my characters as much as possible down south.... there one image is stuck so I am restricted..
"Here in Bollywood, I have nothing to lose so I experiment with my characters. I am thankful to Balki who has given me this film. I don't have anything to lose here."
"It's an amazing experience to work with Amitabh. I don't know if I have done enough work to deserve to be working with Amitabh. God has blessed me with this film," he added.
Actor Kamal Haasan's daughter Akshara Haasan is making her debut with "Shamitabh".
Talking about her experience of working with Big B and Dhanush, she said: "I really look up to Amitabh Bachchan and Dhnaush but when we got on sets, they made me feel very comfortable, they made things easier for me."
