Ace Bollywood film maker Karan Johar was all braced to append some extra sparkle, naughtiness and enjoyment to the second part of his romantic comedy 'Dostana', however, the most recent reports disclose that he might have to drop the film at the moment.

'Dostana' explored the tale of two males who acted to be gay with the aim to rent an apartment house from an older lady.

The movie proved to be a leader and was announced a noisy success. Its sequel 'Dostana 2 was long awaited by the buffs but to their shock the sequel is being postponed at the present.

A source stated, "Karan was very excited about doing the sequel of Dostana, which was announced immediately after Dostana released in theatres in November 2008."

KJo did not shy away from handing details to the media persons regarding formulations for 'Dostana 2' being well under way. But, the film's director Tarun Mansukhani has not been capable of finalizing a screenplay, which Johar is also pleased with.

The movie was being co-produced by Karan Johar's Dharma Productions together with UTV Motion Pictures.

Even though the film's first half has been finalized and everyone is positive, it is the second half, which has been troubling them.

"The film writers and Tarun are not able to put together a better second half than the original," the source added.

In fact, several drafts of the screenplay were made but all were disapproved one by one. The failed attempts are taking a toll on Karan's forbearance it looks; he wants to march on to making other flicks.
