They say Bollywood is one big family. And attending premieres of each other's films certainly a part and parcel of the ways of the tinsel town. In a latest, Amitabh Bachchan has confirmed that Aamir Khan and Shah Rukh Khan will grace the premiere of Paa, where Big B plays a 13-year old boy afflicted by the rare disease progeria.

Bachchan writes on his blog, "And now for the bad news. The London and Dubai premieres stand cancelled. Several issues have cropped up and it would not be prudent to go ahead with it, under such uncertain pressures and circumstances. But Mumbai is on ... at the IMAX Wadala on the 3rd of December and Aamir and Shah Rukh have both assured me of their presence there, today, as I begin to send out letters and requests to block said date from the Industry."

In the same post, Bachchan praised the regional press for their incisive questions and informed fans that he's going to Chennai to "get an idea of the mechanics that go behind a final product - background and sound and effects and titles and sub titles."

Sure, there's a lot that goes behind making a film. Especially, when you have the biggest star of Bollywood in it.
