Actor Ranbir Kapoor has stepped into the shoes of Bollywood's popular 'Khalnayak', and his new pictures from Dutt's biopic are going viral on the internet. In these new pictures, Ranbir can be seen sporting long locks, Sanjay Dutt's 90's look to be precise. Ranbir has phenomenally metamorphed into a middle-aged Sanjay Dutt, with salt and pepper beard and a receding hairline. The pictures are such that one might need to look twice to realise that it's not Sanjay but Ranbir. Ranbir has united with director Raju Hirani for this biopic. The film will focus on Sanjay's formative years, his relation with his father Sunil Dutt, his struggles with the loss of his mother and his affairs.
