Rani Mukherjee's comeback venture Mardaani seems to have hit a snag. Apparently director Pradeep Sarkar was supposed to shoot on Mumbai airport on Thursday evening.

But the necessary permission has been denied.

Says a source from Yashraj, `Rani and her co-star Jisshu Sengupta were supposed to shoot a romantic scene on the Juhu beach early in the morning on Thursday. In the evening they were supposed to do a very emotional sequence on the airport. However the airport sequence had to be cancelled because the necessary permission was not forthcoming.`

The sequence has now been pushed to March-end.

Says the source, `Pradeep has cancelled both the shooting on the beach and the airport sequence on Thursday. He will shoot them both when the airport authorities allow shooting on the airport.In the meanwhile a long schedule for Mardaani is planned in Delhi at the beginning of March.`

It may be pointed out here that shooting in public places in Mumbai is getting more and more difficult.

The very talented Rensil d'Silva who shot his new film Unglee all over Mumbai says, `The formalities are a nightmare. But because I had Karan Johar as a producer it was relatively easier to get those permissions. Otherwise it would have been really difficult.`
