Looks like Nargis Fakhri has run out of luck. After starring opposite Ranbir Kapoor in Rockstar, Nargis had bagged her second film Khiladi 786 opposite Khiladi Kumar. But now the hottie is out of the film. Wonder why?Apparently, Mithun Chakraborthy has to be blamed for Nargis' ouster.A source told Mumbai Mirror, "Nargis was signed by Himesh Reshammiya and Akshay Kumar to play Amitabh's sister in the film. However after Bachchan pulled out, Akshay roped in Mithun to essay the role of gangster Tatya Tukaram Tendulkar. That changed a lot of things."Nargis who was excited about the role had to opt out of the film. There are no ill feelings though."They have decided to keep their options open for a future project that may bring them together. Right now, the hunt is on for a new leading lady," the source added.In the film Paresh Rawal and Himesh Reshammiya play Gujarati characters of Champak Lal and Mansukh and Akshay Kumar plays a Punjabi guy.The film goes on the floors in June and is directed by debutante Ashish R. Mohan.
