Amitabh Bachchan entered the Indian film industry when it was dominated by actors like Rajesh Khanna, Dharmendra, Sunil Dutt and Dev Anand.
While most were comfortable playing the romantic hero, he took up the challenge of doing action films, thus creating a niche for himself.
His success in films like Deewar, Zanjeer and Sholay saw him nicknamed the 'angry young man' of Hindi cinema.

It seems unbelievable that Mr Bachchan was once rejected by broadcaster All India Radio because they did not like his voice.
Ironically, today the actor's deep baritone and impeccable dialogue delivery have acquired iconic status.
He has, in fact, worked as a playback singer for 29 movies and in 2005, even lent his voice as narrator to Luc Jacquet's Oscar-winning French documentary, March of the Penguins.

In 1995, three years into semi-retirement from the film industry, Big B founded Amitabh Bachchan Corporation Limited, an event management and production firm.
Although the company achieved considerable success in its first year thanks to the Miss World Pageant, which it produced in 1996, it was soon mired in controversy.
It subsequently suffered crippling losses, forcing Mr Bachchan to take up acting again in order to cope with massive business debts.

Although Amitabh Bachchan is an experienced professional in his field, he believes that learning is an ongoing process.
He's worked with junior co-stars and directors half his age, but he's never reported to throw tantrums or push his weight around on set or otherwise.
A director's actor, he tells us that one must be eager to learn through life.

Be it his insistence to do action movies or his choice of working on projects like Boom and Nishabd, which bombed at the box office, the actor has always given his 100 per cent, never shying away from criticism or bad reviews.
His dedication to his craft is apparent in the movie Paa. To get into character, Bachchan Senior had to spend four to five hours everyday donning prosthetic makeup, post which he could not eat or drink normally -- and it took two hours after each shoot to get rid of it.
Despite his age and seniority, he did not complain once, which is the mark of a true professional. Paa remains one of his best performances to date.

In an industry where feuds are rampant and superstars often have 'camps' taking sides, Mr Bachchan comes across as one of the more mature and dignified personalities.
To be sure, he has had his share of fall-outs, which are inevitable -- the Gandhi family, Shah Rukh Khan, Amar Singh, Anurag Kashyap, various media publications -- but there's no denying that the senior actor does not believe in mud-slinging and has graciously moved on from most fall-outs, often extending a warm hand of friendship to former nemeses.
He has never used the media as a tool, as so many celebrities often do, to lash out at his detractors.

Amitabh Bachchan is one of the few stars that take their iconic status seriously.
His interactions with his fans and the press are generally warm and gracious, and he makes a visible effort to remain humble and grounded.
Wherever he goes, the paparazzi follow. And despite the constant attention, which can get to the most patient of people, he manages to keep his cool and handles the shutterbug invasion with a smile, posing for them, answering questions and leaving them satisfied.

From his decision to support the nationwide polio campaign to his association with various charity organisations, Amitabh Bachchan has always found the time to give back to society.
n fact, his reputation as a patron of charities is such that the Silver Star Diabetes Centre, a UK-based clinic, presented him with a mobile diabetes-testing unit on behalf of the city of Mumbai as a 70th birthday present.
The first of its kind, the mobile clinic will be named 'Amitabh' in his honour.

Attend any event where Amitabh Bachchan is presiding and chances are you will get to hear him quote a few lines of poetry by his father, the late Harivansh Rai Bachchan.
Big B finds special purpose in revisiting his father's poems -- to him, it's a way of paying tribute to the man who raised him.
In November 2011, on his ninth death anniversary, he tweeted, "In prayer and in thoughts with him ...a great human, great mind, and a great Father!! All that I am is because of him...his guidance, his morals, his culture and his ethics...now just fond memories of his to live with."

They say time is money and that particularly holds true in the movie industry, where an actor's tardiness can cost moviemakers lakhs, if not crores.
B-Town biggies have a notorious reputation for holding up shoots, strolling onto sets five hours late, throwing tantrums that cause setbacks to the schedule and delaying projects by months, sometimes, even years.
Not Amitabh Bachchan. One of very few stars known for their punctuality, he is apologetic even if he's kept you waiting a few short minutes.
