Bollywood megastar Amitabh Bachchan says Shah Rukh Khan left him in a jovial mood after the latter called him to confirm his presence at the premiere of upcoming film "Paa".

"Shah Rukh has remained with me in the late afternoon. He is a very funny man and shakes me into joviality when I inform him about the premiere and his absolute presence there. He tells me, 'He is already there, black suited and with anticipation of seeing 'Paa'," Amitabh posted on his blog.

"Aamir too communicates today and confirms his presence," he added.

The cast and crew of "Paa" - including Amitabh, Abhishek and director R. Balakrishnan have major plans for the film's premiere Dec 3 in Mumbai.

Amitabh plays a 12-year-old progeria patient in "Paa" and he had to stick on several pieces of specially crafted clay to get the right look for the movie. The disease causes premature ageing among children.

International make-up artist Stephan Dupuis designed Big B's look and the megastar had to sit for five-six hours for the make-up.

The 67-year-old says he is now anxious about how the audience and critics will react to the film.

"Slowly but surely the jig saw puzzle will begin to unfold. The test of all our hours and hours of effort at the film shall now be up for scrutiny. And within two hours and 14 minutes the verdict shall be passed. Once passed, shall remain passed. Such is the destiny of those that participate in this wondrous game of filmmaking," he said.

The film is releasing Dec 4.
