Based on Raj Kapoor and Nargis' on and off screen romance, Aditya Chopra's project is at a standstill as of now. He had discussed the idea with Ranbir, who consulted his father Rishi Kapoor, who then turned the idea down.
Rishi also spoke to his brothers Randhir and Rajiv who didn't like the idea either and didn't want to support it. The three brothers told Ranbir that he shouldn't do the film.
They even called up Yash Raj and protested against it by stating that they would appreciate it if they stopped entertaining the idea of making a film on their father's days with Nargis.
According to sources, it's not just the Kapoor brothers who'd be upset with the film. Even Sanjay, Priya and Namrata Dutt (Nargis' children) wouldn't appreciate the film being made. Despite the demand, Raj Kapoor and Nargis' films were never even re-released in colour by RK Films so going ahead with this idea was not something they would do.
