A lot is being talked about Sanjay Dutt’s biopic that will be directed by Rajkumar Hirani. Buzz is that that the film has been tentatively titled ‘Dutt’, but the filmmaker has asked his team to rack their brains and come up with an interesting name. Whoever suggests the best title will apparently be awarded handsomely. The team will start shooting in January and Ranbir Kapoor has already started with the preparations for his strong character. Dutt biopic will bring together Ranbir and Sonam Kapoor after they marked their debut with ‘Saawariya’ in 2007.
