The film is a story of a strong bonding between a brother and a sister. And Priyanka's brother in Zoya's film would be played by none other than Ranveer Singh.
A bit of an odd casting calculation, considering the two play paramours in Yash Raj Film's 'Gunday'. Says a source close to Ranveer, "They are both very accomplished young talents. They will look as convincing as siblings and lovers."
To rewind a bit, Zoya wanted to cast real-life cousins Ranbir and Kareena Kapoor as siblings in her film. The two rejected the offer as too gimmicky.
