The Dubai and London premieres of Amitabh Bachchan's film "Paa" have been cancelled, but the superstar says he is looking forward to the Mumbai event that will be attended by Aamir Khan and Shah Rukh Khan.

"The London and Dubai premiere have been cancelled. Several issues have cropped up and it would not be prudent to go ahead with it under such uncertain pressures and circumstances, " Amitabh posted on his blog www.bigb.bigadda.com.

"But Mumbai premiere is on at the IMAX Wadala on Dec 3 and Aamir and Shah Rukh have assured me of their presence there, " he added.

Apart from promotional events of "Paa", Amitabh is also busy preparing for "Bachchan Sandhya", an event to mark the 102nd birth anniversary of his father Harivansh Rai Bachchan on Nov 28.

"The arrangements, the invitees, the program and its functions, rehearsals for the recitation and getting the family to gear up for its participation is also keeping me busy, " he wrote.
