Bollywood stars Amitabh Bachchan and Aamir Khan are leaving no stone unturned to promote their upcoming films "Paa" and "3 Idiots" respectively - the two are meeting Sunday to discuss marketing gimmicks for both the films.

"Paa" is releasing Dec 4, while "3 Idiots" hits the screens Dec 25.

"Aamir comes over Sunday at my initiative to discuss a few promotional points for our respective films. It is always a joy to meet him... We have always spent time together discussing various topics of common interest and yes films is one of them. Lets see how things go, " Amitabh posted on his blog.

Aamir, who excels at promotional gimmicks for his movies, has so far had live chat with fans on the Internet, reportedly got in touch with them through social-networking websites and even launched the music of the film online.

Directed by Rajkumar Hirani, "3 Idiots" has been produced by Vidhu Vinod Chopra. Based on Chetan Bhagat's bestseller "Five Point Someone", it stars R. Madhavan, Sharman Joshi and Kareena Kapoor apart from Aamir.

Big B too is promoting "Paa", in which he plays a 13-year-old suffering from the disease progeria that causes premature ageing. He says his fans often come to visit him on Sundays and that he plans to "give hand outs autographed by me or maybe by Auro".

"There is a unique way in which the promotion for 'Paa' is scheduled over the radio and soon you shall all be in a position to witness it..., " he wrote.

"Talks have now been initiated for the premiere to be held in not one, not two, but three centres. And we are diligently working on a London-Dubai-Mumbai destination... The logistics and the mechanics are being worked out and hopefully there will be some news soon, " he added.

Directed by R. Balakrishnan, "Paa" stars Abhishek Bachchan and Vidya Balan as Amitabh's parents.
