South superstar Dhanush plays a rough-around-the edges hero in Aanand L Rai's Raanjhanaa, his debut film in Bollywood. Talking about the decision to cast him, the director says, "After Tanu Weds Manu, I had the opportunity of signing some of the biggest names in Bollywood, but I knew right from the scripting stage that my hero had to be Dhanush. I stand vindicated because the trailer has hit the bull's eye. My only concern was the language barrier, but Dhanush bowled me over with his dedication."

When it came to Sonam Kapoor's character, Aanand was looking for someone who is real and desirable. "I was looking for a girl who seemed unattainable to the boys and Sonam has that characteristic. I needed someone high on emotions and she was the ideal choice."With Dhanush as the lead, the makers required someone who could hold his own and this is where the versatile Abhay Deol came in. Says Aanand, "I was always sure of casting him because I am yet to find an actor as dedicated, secure and talented as him. I needed someone very gutsy opposite Dhanush."

Producer Krishika Lulla says, "We needed a non-stereotypical lead pair for Raanjhanaa. Dhanush was a decision made on instinct.We were also looking for someone like Sonam who had great screen presence and made for a beautiful yet grounded character. This is a straight-from-the heart film. We are also fortunate to have Academy Award winner AR Rahman composing for our film."
