After reportedly being signed on for the lead role opposite Aishwarya Rai Bachchan in Madhur Bhandarkar’s Heroine, Arjun Rampal has now been roped in for Tigmanshu Dhulia’s next tentatively titled Jai Ramji alongside Preity Zinta, Irrfan Khan and Randeep Hooda.A source close to the actor reveals that Arjun’s role in the film is that of a cop. “His character is based on a real life police officer from Allahabad. He has been meeting cops to get a deeper understanding of how to essay his role.”On his recent visit to New Delhi, Arjun met police commissioner BK Gupta and a few members of his team to get a first hand account of the job. “Arjun wanted to get the finer nuances of a cop’s life right. He plans on visiting top police officials from the North to ensure he gets the mannerisms right. He doesn’t want challenging roles to have a caricature-like feel,” adds the source. The gangster film, Jai Ramji, is set in UP and is expected to go on the floors in July.
