Ram Gopal Verma's Sarkar 3 has become flash point between Ranbir Kapoor and the maverick director. According to sources the actor refused RGV's offer to play Amitabh Bachchan's grandson in the upcoming political thriller.

“Ranbir was best suited to play Kay Kay Menon`s son in ‘Sarkar 3’, which would have seen Amitabh coaching his grandson to take over the powerful Subhash Nagre empire. Ramu was really impressed by Ranbir and approached him with the offer, but Ranbir wasn`t too excited about the film. In fact, he flatly refused to do it, ” says a source.
