New Delhi, Jul 31 (IANS): Bollywood actors Saif Ali Khan and Deepika Padukone will appear as special guests on the fifth season of the game show "Kaun Banega Crorepati", which starts off August 15 with megastar Amitabh Bachchan as the host.

"One interesting candidate and the entire anxiety of the working of the show just flies past .. we had a few today and tomorrow is another day .. let us hope that all goes well .. the second episode towards the evening will have invites to Saif and Deepika .. who come to promote their film and mine as well - 'Aarakshan' !!!"Amitabh posted on his blog bigb.bigadda.com.

"In many ways, the philosophy of the film and that of KBC is quite similar. Given opportunity, even the lesser privileged shall prosper. Or at least have the capacity to prosper," he wrote.

However, Mumbai rains played spoilsport as the production unit had to stall the shooting of the show several times due to the noise of the rain.

"The rains have been incessant.. and so harsh that we had to stop shooting KBC at times, because of the noise factor. But all in all a most satisfying day … harsh and hard, but satisfactory," Amitabh said.

Saif had previously appeared with actress Preity Zinta in the second season of the show, while Deepika came as a guest last year although she didn't play.
