Everybody knows that Sanjay Dutt was born with the silver spoon, did enough drugs that his body gave way. When everybody thought he’ll crimple he gave a tough fight and was named Rocky. He went on to make 308 girlfriends and took an AK 47 by his side. A rollercoaster ride that superstar had is tale people have been waiting for.

And as the wait ends with the very first teaser of Sanju, Ranbir Kapoor looks stunningly similar to the controversial actor. He has clearly stepped into the shoes of the Sanjay Dutt that it is almost impossible to take your eyes off him.

Taking us through different stages of Sanjay right from the beginning when he was merely 22 years old till date that he is 58, Ranbir gives a glimpse of each stage effortlessly.

Written and directed by Rajkumar Hirani, the film stars, Ranbir Kapoor with Anushka Sharma, Paresh Rawal, Sonam Kapoor, Dia Mirza, Karishma Tanna, Manisha Koirala, Jim Sarbh, Vicky Kaushal and Boman Irani are also part of the film.

Ranbir worked hard on his physique for the film and transformed for various phases of Sanjay’s life. Earlier Ranbir said, “Getting the look right is very superficial, it is easy as you have help from make-up and computer graphics. To show Sanjay Dutt as a human being, as a biopic only works when you show the human side of a person -- and not the glories but the downfall as well, was not easy”. The team underwent tremendous research for the film including watching more than 200 hours of footage for the film.

Earlier, talking about a biopic on his life, Sanjay had said in an interview, "I have not had an easy life. I have made way too many mistakes, and I want youngsters to really learn from it. So, if you ask me, it was definitely worth telling my story, because I want it to make a difference to the generation today.”

Talking about the film’s title, Hirani told a leading daily, “Actually, we thought of many titles. One of them was Aisa Hi Hoon. Anything you attach with a name in a biopic is like an adjective. Even if you say Aisa Hi Hoon or Sarphira, either you are glorifying him or attacking him. One thing all of us were clear about was that we wanted a neutral title. Dutt seemed a little harsh. Then I heard a gem from him. Apparently, Nargisji used to call him ‘Sanju’ with a lot of affection. We thought this is the most non-committal and neutral title, with no pre-conceived notions.”
