Raj Kumar Gupta is planning a film on the story of India’s RAW (Research and Analysis Wing) agent Ravinder Kaushik, also known as Black Tiger, and the filmmaker is keen to cast Hrithik Roshan in the lead role. Buzz suggests that Raj Kumar Gupta is soon going to give a narration to Hrithik, after which the actor will decide whether to play the secret service agent or not. Ravinder Kaushik, alias Black Tiger, was sent to Pakistan on a major undercover mission at the young age of 23! Raj Kumar Gupta, who made ‘No One Killed Jessica’ and ‘Raid’ inspired from real life incidents, will follow similar approach to his film on Black Tiger.
