The 72-year-old star, who is returning on Star Plus after over 15 years, was on stage when the blaze broke out. The shoot was stopped for around 45 minutes.
According to a source, softie light got overheated which caused the minor fire. Taking control of the situation, Amitabh tried to calm the crew members.
"Amitabh was onstage. He calmed everyone down. After controlling the fire, everyone present on the stage said 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 avatar of Big B, who makes a simple ride in an elevator interesting with an impromptu jig and crazy antics.
Amitabh has turned all his attention to the show. He is personally looking into every aspect of the show -- be it creative, music and content. The show will premiere on October 18.
And actress-entrepreneur Shilpa Shetty Kundra will be appearing on the first episode of the show as she tweeted: "On the sets with srbachchan, he has an aura about him that makes every heart skip a beat, mine too."
She also shared an image, in which she is posing with the cine icon in a traditional attire.
