to Chopra's stardom. Basu explained "I had the fear that I would see Priyanka Chopra in the character and Jhilmil wouldn’t work. This has happened in many films where known faces have harmed the character." Priyanka Chopra was cast to play the part but, the development was not announced as Basu wanted to workshop first and see how it goes. After three days of workshop, Basu was convinced that Chopra could play the autistic part and reflected that he was glad that he chose Chopra for the role. Later, Basu revealed that he did not approach any actress other than Chopra for the autistic part. After Chopra was cast in the film, Kaif left the project for unknown reasons. Media reported that she may have opted out of the film because Chopra had been given a stronger role. Later, media reported that Asin Thottumkal was approached to play the role of the narrator, replacing Kaif. However, Asin was never signed to the project. Media reported that no other actress wanted to sign for the film because according to them, the autistic part was stronger. In July 2010, Mumbai Mirror reported that Chopra was ready to play the role of narrator and leave the autistic role, so that another actress could be cast in the film; Chopra did not want the film to stall. Basu confirmed this development and said, "It's true we’ve been unable to cast the other part." After facing several casting problems, Basu chose to cast a completely new fresh face to play the second female role. In early December 2010, Ileana D'Cruz, a popular actress from South Indian films, was finalised for the second female lead, featuring as narrator and Kapoor's first love interest in the film, thus making her debut in Bollywood with the film. Characters Kapoor played the role of a deaf and mute man in the film. According to Kapoor, he took inspiration from screen legends such as Roberto Benigni, Charlie Chaplin and his grandfather Raj Kapoor. Due to the protagonist's physical disability, Basu did not want to use any sign-language but, some behavioral patterns in the film. Kapoor described his character as a regular, happy-go-lucky and good hearted guy. Chopra played the role of Jhilmil. Basu described Chopra's role as the "toughest" in the film. In order to prepare for the role, Chopra visited several mental institutions and spent time with autistic people.
