Mumbai, March 1 -- Rajkumar Hirani's biopic on actor Sanjay Dutt has got a lot of attention before it can even go on the floors. We've learnt that the film-maker is finishing the script in the US.
After the success of PK (2014), Hirani was flooded with calls and messages. A lot of people were dropping in to meet him too. "This was disturbing him, and scripting the biopic was getting difficult," says a source.
In fact, in an earlier interview to HT Cafe, Hirani had mentioned that several changes were required in the script before shooting would commence with lead actor Ranbir Kapoor.
The film-maker is not expected to return to Mumbai till the end of March. The source adds, "Apart from his family and close friends, no one is aware of where he is. The script demands his undivided attention."
