So what if Department flopped, RGV is still a hit in the department of tweet wars. The failure of the Amitabh Bachchan - Sanjay Dutt starrer has shaken up the films director Ram Gopal Varma so bad that he is spitting venom against Dutt and the CEO of his production house, Dharam Uberoi, after Dutt told media that RGV was responsible for the debacle and that he wont work with him again.Whatever else happening to Department I am supremley happy tht I dont nd 2 see the faces of Sanjay dutt nd Dharam uberoi fr rest of my life. Frm forcing me 2 take Kangana (actor Kangna Ranaut) out of the film 2 constantly cornering me 2 change screenplay I had the most horrible time wrking wth Dutt (sic), tweeted Varma on Tuesday.Dutt and his aide have their share of mud to sling. Ramu has lost it, he himself does not know who to make movies with, he is a conman. I wish he had paid attention to movie-making instead of sending weird messages to girls around him, says Uberoi. The war between Dutt and Varma has been on ever since Dutt signed the movie. Sanjay and Ramu were at loggerheads from the beginning. Sanjay and Dharam used to interfere a lot during the filming. And this is not the only movie where Dutt did not let Kangna work. Ever since she fought with Ajay Devgn on the sets of Rascals, Dutt and Ajay have taken away many projects from her, says a source from the films unit. Devgn, however, denies. Alls well between Kangna and me,he says. Dutt had earlier clarified on the issue of casting Kangna by saying, I was not involved in casting or changing the screenplay of the film. I followed Ramus cues. As per the script, we didnt need any leading lady in this film.
