Ram Gopal Varma is caught in the cross-fire. Has Shah Rukh walked out of his Time Machine? Apparently Shah Rukh Khan is miffed with director Ram Gopal Varma. The actor is said to be unhappy about the fact that instead of going ahead with the pre-production of Time Machine, Ramu has begun shooting for a quick film, Nishabd, with Amitabh Bachchan. Incidentally, Ram Gopal Varma has been chasing Shah Rukh since the last five years. Ramu offered him several films, which Shah Rukh turned down. But finally, Shah Rukh decided to work with Ram Gopal Varma because he is open to experimental films since Paheli. Earlier Shah Rukh had stated that he didn't want to work with Ramu because the director makes 'dark films'. According to sources close to Shah Rukh, “Shah Rukh was surprised to read about Nishabd in the newspapers. He thought that Ramu was working on his film Time Machine, but when Shah Rukh realised that he's actually making another film with Amitabh Bachchan, he was taken aback.” Apparently Shah Rukh called up Ramu to ask about the project, and was informed by the filmmaker that he is making a 'quick film' with Amitabh. “Shah Rukh was disappointed with Ramu because he expects his filmmakers to spend time on pre-production for his films, especially since he maintains his exclusivity and works in one film at a time,” says our source. Currently shooting for Don in Malaysia, the actor was supposed to start working with Ramu from August. When he realised that Ramu was making another film while he was shooting for Farhan's Don, he called and requested him to start the pre-production. “Shah Rukh doesn't have a problem with Nishabd or any other film Ramu wants to make. He just doesn't want to compromise on his film,” says our source. The buzz goes that Shah Rukh's anger is part of the on-going Bachchan-SRK war. However our source denies the rumour saying, “Shah Rukh respects Amitji. In fact, he is working in Don which is a remake of Mr Bachchan's film. He is very close to the family. It's just that he is a very dedicated actor and expects a lot of commitment from his filmmakers too. If Ramu promises him that commitment, Shah Rukh will happily do the film.” Last heard Ramu has started working on the pre-production of Time Machine, along with shooting for Nishabd in Kerala. Evidently, he wants to keep both Bachchan and SRK happy.
