Aishwarya and Abhishek last starred together in Mani Ratnam's Raavan
Abhishek Bachchan and Aishwarya Rai Bachchan were to team up for Shailesh R Singh's production last year.
There was a lot of curiosity about the project as they were to play a cop couple in the thriller. The latest is that the makers have tweaked the script on Ash's suggestion.
The duo will be given a joint narration soon.
The makers are hopeful that they will give their final nod and the film rolls later this year.
