The 71-year-old, who has been the host of KBC for all the seasons expect for third, posted on his blog that the filming process on the last day happens amid a lot of cheering from the audience.
"Tomorrow is a very early start again and an entire day of screaming activity... It's the last episode of this season and that takes time..!!," Bachchan wrote around midnight.
He also urged his fans not to bring too many presents for him as their presence is enough for him.
Bachchan had earlier posted that he would get busy with the shooting of 'Bhootnath Returns' and Anurag Kashyap directed TV show after wrapping up KBC.
