It looks like the glam dream of seeing the three gen-X superstars Shahid Kapoor, Ranbir Kapoor and Imran Khan locked in a battle to the finish would remain just a fantasy. The expected clash Sep 9 this year between Shahid's "Mausam", Ranbir's "Rockstar" and Imran's "Mere Brother Ki Dulhan" is not happening!

Though official sources claim otherwise, director Imtiaz Ali's "Rockstar" has been moved forward to November.

There seems to be no limit to the delays being caused in the release of "Rock Star". Though officially the latest release date is Sep 9, there is no doubt the film has been secretly shifted to November and it looks like there are chances of further delays.

In fact a source very close to the project confirms "Rock Star" has been shifted to November.

"For now we've shifted to November. But this again is not sure. We could move further ahead, " he says.

But producers Eros International maintain the status quo on the release.

Says Ram Mirchandani of Eros: "As of now we are not in a position to comment on whether the release date has been shifted from Sep 9. As soon as we get a clearer picture we will let you know."

The latest buzz is that "Rock Star" may not be released this year at all. It could now be released at the beginning of 2012. The main reason for the delay is said to be the music of the film.

Says the source: "A.R. Rahman has still to do a couple of tunes and the full background music. However, Imtiaz is really happy with the music that Rahman has done so far. In fact, Imtiaz knows the musical film is being transported to another level, thanks to Rahman's music.

The delay in the release is getting too expensive, he adds.

"The delay is proving expensive to the film's producers Eros International and Shree Ashtavinayak. It's also Nargis Fakhri's debut film. And she's getting anxious to sign other films. She's flooded with offers. But as per her contract, she can't sign any other film until 'Rock Star' releases, " he says.

The biggest sufferer is Anurag Basu and his producer UTV, whose dates for Ranbir Kapoor in "Barfi" keep getting allotted to Imtiaz Ali's "Rock Star".

With "Rockstar" songs yet to be delivered, it looks like Basu's "Barfi" may yet have to suffer some more date-adjustment hassles.
