John-Bipasha starrer plotted around 9/11 attacks

September 11 attacks on the symbols of USA seem to be inspiring many filmmakers. Mumkin is also about the attacks where Bips is a painter and her elder sister is killed. Her search for more information on the counter-terrorism operations leads her to John Abraham, who is an expert in counter-terrorism. Budgeted around Rs. 6 crore, the film is said to have appealed to Abraham, since one of his friend had done a similar role in real life and laid down his life for the same. On the other hand, Basu is keen on shedding off her sexiest image for more challenging roles. "It is unfortunate that I have got the sex symbol image after Jism", says Basu.
