Ranbir Kapoor, who will soon be seen as Sanjay Dutt in the latter’s biopic, may soon share the frame with Dutt. According to trade buzz, director Karan Malhotra has cast Ranbir in his next project and has also approached Sanjay Dutt to play a part in the film. Apparently, Ranbir will play Sanjay Dutt’s son in this project, which is produced by Yash Raj Films. If Sanjay Dutt, who is being choosy about his Bollywood projects of late, gives nod to this film then it will be his first venture with the coveted Yash Raj banner. Rumours suggest that Vaani Kapoor may be cast opposite Ranbir in this film.
