The line saying which says introducing in the movie is the most important line that an actor sees in his career. Amitabh Bachchan with the release of his next movie Paa will become one of the few actors who will see the line for the second time in his career. In the credits of the movie Paa, it will read Introducing Amitabh Bachchan.

Now the reason for that is simple Amitabh plays a boy named Auro in the movie and the director of the movie is ready to bet on this that people will not be able to recognize him at once when they first see him on screen. He will be presenting to the audiences Big B in a never before seen avatar. In the movie, Amitabh plays this 12-year-old kid and he went so deep inside the skin of his character that sometimes he had to be taken to task or stopped from doing things to keep the discipline.

The character he plays in the movie suffers from Progeria, which is a rare disease in which the person ages quickly. Eating chocolates is known to slow down the process so it was required of him to eat a chocolates which is not what his real health situation permits but when it was required on screen he would much on chocolates just like a kid. Vidya Balan and Abhishek Bachchan who play the character of his parents will have normal credits reading starring.

They will not be using Progeria to promote or market the movie as Progeria Research Foundation does not want a wrong image to be created in the minds of the audiences. They will be making a donation to help fund the research and treatment at the foundation.
