Basking in the National Award glory for his unconventional role in Paa, megastar Amitabh Bachchan, who turned 68 today, is still going strong and continues to be the busiest actor of his generation in the Hindi film industry.

It has been a mixed year for the legendary actor, who is hosting the fourth edition of the popular quiz show Kaun Banega Crorepati (KBC), which incidentally played a key role in reviving his flagging Bollywood career a decade ago.      

He was seen in different avatars in his latest releases even though the movies did not ring well at the box office.      

In Aladin, which released in October last year, he was seen as a genie; Teen Patti featured him as a mathematics genius along with noted actor Ben Kingsley. His home production Paa', which saw him playing a child suffering from progeria causing pre-mature ageing, was a box office grosser.

The film fetched Bachchan a national award this year.      

It was on his 66th birthday in 2008 that there was a health alarm when Big B was hospitalised due to abdominal pain and had to be operated following which he did not sign any new film in the last one year and only hosted season three of hit reality show 'Bigg Boss' for Colors.

This year, the legendary actor is back facing cameras for Rajkumar Santoshi's Power with Sanjay Dutt, Ajay Devgn and Anil Kapoor. Besides, he is also back on small screen as the host of 'KBC' on Sony.

The channel is hosting a party for Bachchan on Monday night with the first episode going on air.
