Abhishek Bachchan and gorgeous wife Aishwarya Rai Bachchan are in high-demand these days. Producers flock in herds with scripts in hand to cast Bollywood�s most popular couple in their movie.

Sources say that a very reputed production house has come up with the idea of making a period flick on Shah Jahan and Mumtaz and they are hell bent on casting Abhishek and Aishwarya only for the role.

Aishwarya Rai was the obvious choice for Mumtaz because the source at the production house claims that she is �flawless beauty� just like Mumtaz who could inspire her lover to build the magnificent Taj Mahal in her memory. And since Abhishek and Aishwarya Rai make a very popular and adored couple off-screen they thought they would cash in on their chemistry.

I wonder if that would be a good idea� Abhishek Bachchan and Aishwarya Rai haven�t been very impressive lovers on screen.
