There may be a few more wrinkles on his face and his health does disobey him often, but his dedication and power to give justice to his characters make him the Big B of Bollywood.
"It is past midnight ! It is my birthday today ! It is another year gone by ! It is stepping in to the 70th year for me ! Thank you !" he tweeted to his fans.
"They ask me what I wish for my birthday .. why only on the birthday, it should be everyday .. I wish another day to pass in peace," he remarked.
Big B is known for his passion towards his work and this is reflected in his tweet: "One of the best ways to bring in birthdays is to be working at what you need to be working on .. I work because I need to .. love !!
His recently released film ‘Bbuddah... Hoga Tera Baap' perhaps reflected the true colours of the evergreen hero with a powerful voice, where he was seen dancing around in the remixed versions of his own popular numbers.
Recently he was seen releasing a CD of Hanuman Chalisa that included one composition sung by the legend himself. Twenty other singers had rendered their voice in the album.
"Just launched Hanuman Chalisa CD composed by Aadesh Srivastav sung by 20 playback singers of Industry and myself .. Feel blessed !" he tweeted on Oct 9.
The religious album is composed by Aadesh Shrivastava under AB Corp and Veecon Music and Entertainment. Srivastava was present at the venue.
"Reeling with the emotion of the CD release of Hanuman Chalisa ..happy with the efficient way it was conducted..well done GS and AB (AB Corp)," he tweeted.
In his long career Bachchan has mesmerised his fans in numerous avatars that ranged from a love-torn hero in Silsila to a angry young man in ‘Zanjeer' or ‘Deewar'. His charismatic performance was seen in the films that he did in his later years that include names like ‘Cheeni Kum' or ‘Nishabd'.
In both the films he was shown as an old man romancing a young lady. In ‘Paa' Big B was seen playing one of the challenging roles of his career as he portrayed a character of a progeria affected child ‘Auro'.
Bachchan was hugely appreciated by his fans and critics for his power-packed performance and even grabbed National Film Award for Best Actor for it.
In the arena of Television, Bachchan has been equally successful as an anchor.
His ‘Kaun Banega Crorepati' (KBC) is considered to be one of biggest game shows ever run in Indian television. Even today people wait with equal anticipation to catch a glimpse of Big B anchoring the game show as they used to do in 2000, when the show was first telecasted.
He had also hosted a season of popular reality show ‘Bigg Boss'.Currently he is hosting the fifth season of KBC.
