Bollywood heartthrob Ranbir Kapoor, who is reprising Sanjay Dutt in a Hindi biopic on the controversial actor's life, looks heavier than usual these days. He says he has never before put on so much weight. "It has been an inspiring journey for me to be playing Sanjay Dutt for the silver screen. I have never put on so much weight before and now plan to reduce some weight for the next phase of shooting," Ranbir said at the launch of India's first HP Virtual Reality (VR) lounge at PVR ECX, Mall of India here on Monday. The yet untitled film, being directed by Rajkumar Hirani, would portray seven different phases of Sanjay Dutt's life, starting from when he was all of 22. "It's amazing to be working with a director like Rajkumar Hirani," Ranbir, who looked dapper in a gray suit and sky blue shirt, said at the event.
