Just days after opening up about one of the “most difficult phases” of his life, one that saw him undergo surgery and spend time in the ICU, Amitabh Bachchan has once again demonstrated why he remains one of Indian cinema’s most enduring professionals.

The 83-year-old megastar has revealed that he recently completed a gruelling 24-hour work shift for the upcoming season of Kaun Banega Crorepati, choosing to push through an around-the-clock schedule rather than delay production.

For an actor who has spent over five decades in the industry, the revelation is a reminder of the work ethic and sense of commitment that have defined Bachchan’s career, even at an age when many of his contemporaries have long stepped away from demanding schedules.

A full day, and night, on the KBC set

Taking to his personal blog, Bachchan shared that he worked continuously from 7 am one day until 7 am the next, explaining that the assignment could not be postponed because of the show’s production timeline.

“Aaaahhhh… got hold of time in time… finished work at 7 am this morning… of work that began at 7 am yesterday… but the importance of its presentation and its timely work was necessary… so DID IT,” he wrote.

After wrapping up the marathon schedule, the actor admitted he was looking forward to catching up on some sleep before another early morning call.

“But more the relief of having connected with the daily routine of the Blog and the Ef… I shall retire now, get some food in the belly… hit a pillow for a while for, tomorrow the 6th Aug is another early call…”

‘Missing that would mean a job replacement’

Bachchan also revealed that with the premiere date of Kaun Banega Crorepati Season 18 now confirmed, skipping work was never really an option.

“The first Broadcast Date for KBC is announced… and missing that would mean a job replacement for me. So off to do what needs to be done,” he wrote, adding his trademark touch of humour.

While the remark was made light-heartedly, it reflects the philosophy that has earned Bachchan a reputation as one of the industry’s most disciplined professionals—showing up, delivering on time and treating every project with the seriousness of someone still proving himself.

Coming after a difficult health battle

The demanding schedule becomes even more remarkable considering Bachchan’s recent health update.

Last month, the veteran actor revealed that he had undergone surgery and spent time in the intensive care unit, describing it as the “most difficult phase” of his life. Although he did not disclose details about the procedure, he reflected on the emotional and physical challenges of recovery, calling it a period that tested him deeply.

His return to a packed filming schedule so soon afterwards has drawn admiration from fans, who have praised his resilience and unwavering dedication to work.

A lesson in consistency, not just hard work

In an era that increasingly values work-life balance, Bachchan’s 24-hour shift is less about glorifying overwork and more about the rare level of commitment he continues to bring to his craft.

Even after decades at the top, he approaches his assignments with the urgency of someone who still refuses to take opportunities for granted. Whether it’s maintaining his daily blog, staying connected with fans, or ensuring Kaun Banega Crorepati remains on schedule, Bachchan’s approach has remained remarkably consistent.

When does KBC 18 premiere?

Kaun Banega Crorepati Season 18 will premiere on August 10 at 9 pm on Sony Entertainment Television and Sony LIV. The new season carries the theme ‘Sochna Padega’, highlighting the idea that in an age where information is easily accessible, true advantage lies in the ability to interpret, connect and apply knowledge.
