Ranbir Kapoor can easily be mistaken as Sanjay Dutt, going by the latest look of the actor donning a mustache and huge ‘tika’ on forehead. Ranbir seems to be totally enjoying his new style for the Dutt biopic. “I can never become Sanju Baba, but I am really enjoying this role of his life, his journey. And to work with Raju sir (Rajkumar Hirani), it is like a dream come true,” says the excited actor. Ranbir is currently shooting for a few important sequences at Sanjay Dutt’s home in Imperial Heights in suburban Mumbai.
