Saat Hindustaani, the first movie of Bollywood megastar Amitabh Bachchan, was released on November 7, 1969. Though the movie was not a hit, and the a dozen odd films that followed also bombed, they heralded the era of a superstar, whose stardom has not dimmed on the marquee in the five decades.
Bachchan continues to be one of the busiest actors in the industry as he completes 50 years in cinema.
Calling himself not just a son but also a fan, Abhishek Bachchan congratulated his father on his golden jubilee in Indian cinema.
"Not just as a son, but as an actor and a fan... We are all blessed to witness greatness! There is so much to admire, to learn and even more to appreciate," Abhishek wrote on social media alongside a black and white picture of his father.
"Several generations of cinema lovers get to say we lived in the times of BACHCHAN!!! Congratulations Pa on completing 50 years in the Film industry. We now await the next 50! Love you," the actor added.
"He will remain the most inspiring story in the world of entertainment! Words alone cannot describe his achievements...we are all honoured to be able to watch his genius unravel in front of our eyes," wrote Karan Johar.
"There are stars ...then superstars ...and then there is Amitabh Bachchan," tweeted Ekta Kapoor.
The actor, meanwhile, shared a health update with his fans, saying doctors have advised him to cut back on work.
Sharing several of his pictures alongside a photograph of a meeting with doctors at his home, Jalsa, Bachchan said he would be back to the grind despite the warning by "the stethoscope dressed messengers from heaven".
The 77-year-old star was announced as the recipient of the Dadasaheb Phalke award, Indian cinema's highest honour for an artiste, in October this year.
Bachchan has a busy schedule ahead with Jhun", Chehre, Gulabo Sitabo and Brahmastra.
