Papanasam is Kamal Haasan's much awaited film and the hype in the Malayalam market is unprecedented. The distributors of Papanasam for North India were keen to have a special screening of the film in Mumbai. They planned to hold it a day before its release, on the 2nd.
Unfortunately they did not realise that it is Gautami's birthday was on that day. So Kamal Haasan will not be able to make it.
