Ranbir Kapoor has phenomenally transformed to an older Sanjay Dutt

Mumbai: Ranbir Kapoor inarguably is among the top young lead actors in the country today, largely owing to his immense talent and versatility.

However, Rajkumar Hirani's upcoming biopic on mercurial actor Sanjay Dutt remains his biggest and most sensational project till date, where he will be seen playing the eponymous star.

While pictures of Ranbir sporting long locks, a la 90's Sanjay Dutt had gone viral, the actor has pulled a shocker with his latest look for the film.

Ranbir has phenomenally metamorphosed into a middle-aged Sanjay Dutt, with a salt and pepper beard and a receding hairline.

The pictures are such that one might need to look twice to realise it's not Sanjay.

The film, which also stars Paresh Rawal, Manisha Koirala, Dia Mirza, Sonam Kapoor, vicky Kaushal and Anushka Sharma, is slated for a Christmas release, and already has generated sky high hype.

However, the film will face some tough competition in Salman Khan's 'Tiger Zinda Hai,' which is all set to clash with the biopic during the Christmas weekend.

But for now, let's just admire Ranbir's transformation.
