Ranbir wanted dad to play cop

A source close to the production reveals, "Ranbir was on board from the time he heard the script. When Abhinav said that they had to cast a senior actor to play a cop, Ranbir simply said that his father had never played a policeman in his (40-yearlong) career. That caught everyone's attention."
Now, of course, thanks to that, the Kapoor trio (Ranbir, Rishi and Neetu) will be seen together in the film for the first time.

Ask Abhinav about this and he says, "I am excited to have all three of them in my film. I didn't know that Rishiji had never played a cop in his entire career. I was so excited to have Rishiji and Neetuji play cops for the first time."
