Wake Up Sid

Both Ranbir Kapoor and Konkona Sen Sharma won rave reviews for their performances, and the film emerged as a critical and commercial success. Ranbir Kapoor was the original choice for the lead role. Director Ayan Mukerji wrote the film keeping him in his mind. Konkona Sen Sharma was the original choice for the role of Aisha Banerjee. In an Interview to a TV channel, Ranbir said that Ayan had already thought about casting her in the film but he didn't tell that to him. However, after the narration of the script it was Ranbir himself who coincidentally recommended Konkona's name to Ayan mainly because she suited the character and no other actress from his generation could have played Aisha better than Konkona. Ayan Mukherji took around one and a half year to write the story, script and screenplay of the movie. He then narrated the script to Karan Johar who approved the script in one narration and decided to produce it. The song "Iktara" was not originally used in the soundtrack. Ranbir loved the song in the background and he wanted to use the song officially in some other film, if it is not used properly in the film. However, later the song was used in two different versions - Female and Male that were picturized on Konkona and Ranbir respectively.
