Question

There's a common trope in Bollywood where teenagers are played by adult actors. But which TV show or movie set the absolute record in terms of the age difference between the role and the actor?

Answer 1

Aamir Khan was 51 when he played the role of a 19 year old boy in Dangal. Aamir Khan has done it again what he does the best. The PK actor has gone through a drastic makeover for his film, Dangal, in which he played three different stages, he played the role of a 19-year-old, 29-year-old and 55-year-old.

Another example, Amitabh Bachchan was 67 years old when he played the role of a 12 year old boy suffering from a rare genetic disorder called progeria in Paa. He played the character name called Auro , is an intelligent and witty 12-year-old boy with an extremely rare genetic disorder called progeria. Mentally he is twelve and very normal, but physically he looks five times older.
Though, in this case, the character he played was supposed to look like an old man.
