For "Paa," veteran Indian superstar Amitabh Bachchan submitted to four hours of makeup to turn him into a 12-year-old boy named Auro, who is afflicted with a rare genetic defect that accelerates the aging process so rapidly that he looks nearly 80. Although the makeup, involving a large prosthetic head, is pretty good, it wasn't worth the effort, for the film is no more than a tedious, over-long Bollywood soap opera.
Handsome Amol (Abhishek Bachchan, Amitabh's son) and beautiful Vidya (Vidya Balan) meet at Oxford -- or Cambridge, since settings at both universities are used. Amol pursues Vidya, even though he plans to concentrate solely on becoming a reforming politician back in India. In any event, Vidya becomes pregnant, the couple break up -- but Vidya does not have the abortion Amol thinks she has had. Vidya becomes a gynecologist in Lucknow and raises Auro with the help of her mother (Arundhati Naag.) while Amol, also living in Lucknow, becomes a crusading member of Parliament.
With a loving mother and grandmother and attending a posh private school, where he is treated kindly, Auro, who is precocious and witty, is happy. It is there, at an awards ceremony, that father and son cross paths and the politician takes an interest in Auro, unaware that he is actually his son.
