Amitabh Bachchan is finally beginning the much-awaited Kaun Banega Crorepati shoot, starting September 21. A source says, "We are going to start our first five-day schedule on September 21. We hope to finish canning at least 10 episodes. A huge set has been erected in Film City. The auditions were very good and we are really happy about it. We will mostly not have celebrities in first schedule as of now; we intend to shoot all 10 episodes with commoners. The show will go on air from October 11, on Amitji's birthday. It will be a Monday-Thursday show at 9 pm. Our second schedule is likely to start on October 4 and will go on till October 9. In the second schedule we may have few celebrities.” It is going to be a one hour show. This season, the makers have brought in a few changes in the format. The last phase of auditions in Mumbai got over last week.
