Actor Anushka Sharma plays director Rajkumar Hirani in Sanju. He's said so himself. She's an international bestselling writer, instead of a filmmaker, of course. Since Sanjay Dutt can't write, and generally people don't read books, as he puts it in the film, both Dutt and his wife chase down Sharma's character, who's reluctant throughout, so she can put out his own version of the truths of his life based on interviews held with him, and others, too.

Now if the film is indeed an authorised biopic, one would rightly assume the events taking place in it are all true, and therefore it appears, it took Dutt a lot of cajoling to get Hirani to film his version.
