Ranbir Kapoor has gained a lot of weight to portray Sanjay Dutt on the silver screen in his biopic, and the celebrity actor doesn’t seem to be enjoying all these extra kilos! “I have never gained so much of weight in my life. My face is completely bloated! But now that we have finished 60 percent of the film, I will begin with the process of losing all the weight to shoot Sanjay Dutt from the ’80s,” informs Ranbir Kapoor. The ‘Barfi!’ star confesses that the Sanjay Dutt biopic has been an enriching journey, “It has been an amazing experience to work with a director like Rajkumar Hirani and play Sanjay Dutt, indeed an inspiring journey for me.” Ranbir Kapoor will now lose weight to look like the slimmer version of Sanjay Dutt, when he was 22 years old. The yet untitled Sanjay Dutt biopic will feature Ranbir Kapoor in six to seven different looks, tracing the senior celebrity’s journey from his films to controversies to marriage and finally coming out of the jail.
