The 72-year-old star, who is returning on Star Plus after over 15 years, was on stage when the blaze set out, following which the shoot was stopped for around 45 minutes.
According to a source, an overheated studio light caused the minor fire. Taking control of the situation, Mr Bachchan tried to calm the crew members.
"Mr Bachchan was onstage. He calmed everyone down. After controlling the fire, everyone present on the stage said that it's supposed to be a good omen for a great show," the source said.
The concept of Aaj Ki Raat Hai Zindagi is not known but its trailer gives a glimpse of a fun-filled persona of Big B. The promo of the show has Mr Bachchan break into an impromptu dance gig while in an elevator. (Also Read: Is There Anything Amitabh Bachchan Cannot Do? Now, He Choreographs)
