Tamil actor Dhanush, who is awaiting the release of his upcoming Bollywood film "Shamitabh" with Amitabh Bachchan, has good reasons to experiment with his roles in Hindi films. 

"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," Dhanush said on Tuesday.

When asked why he prefers roles in Bollywood films that are different from his larger-than-life roles in Tamil films, the "Raanjhanaa" actor said, "I have been trying to mix my characters as much as possible down south.... there one image is stuck so I am restricted."

Meanwhile, the makers of the upcoming film, directed by R Balki, released the movie's trailer on Tuesday and it has been receiving overwhelming response from fans, with more than three lakh people viewing it within a day.

"Shamitabh", which also marks the debut of Kamal Haasan's daughter Akshara Haasan, is set to hit the screens on 6 February. While Ilaiyaraaja has composed the soundtrack album and background score, PC Sreeram has handled the cinematography.

Meanwhile, Dhanush will be seen in four upcoming Tamil films, "Anegan", "Vai Raja Vai", "Maari" and "Soodhadi".
