Sources said Alia is currently shooting for Vikas Bahl's Shandaar and will then move to two other projects - Ayan Mukherji's next starring Ranbir Kapoor and Mohit Suri's Half Girlfriend.
Farhan, on the other hand, has allotted his dates to Dev Benegal's Bombay Samurai. This would be followed by Bejoy Nambiar's Wazir.
A source close to the development says, "The Rock On!! sequel was slated to go on the floors by this year end but has been pushed ahead as of now. Neither Farhan nor Alia are free to shoot at the moment. We will get rolling only in January, 2015."
Abhishek Kapoor and Pubali Chaudhuri, the co-writers of Rock On!!, are also engaged in a credit dispute relating to the sequel's script. Read more. Reportedly, Abhishek, who also directed the 2008 film, had a fall-out with the production company over creative differences.
The latter then approached Pubali to work on the sequel and she registered the script with the Film Writers' Association claiming that it was her solo creation. This led to a tiff with Abhishek and the dispute is yet to be resolved.
With Abhishek out of the picture, Shujaat Saudagar of Boot Polissh Films has been roped in to direct the sequel. Farhan and Alia were not available for comment.
