I ran into an actor friend of mine who told me she played Indira Gandhi 7 times in 4 different films in different languages. This got me thinking. What goes into the casting of a famous person? How many Mrs Gs are too many? Do you have to look like that person?
Bollywood is famous for legends about the same actor playing the same role. The most notable (perhaps untrue) nugget is about Iftekhar, who played a police commissioner so often in the 1970s-1980s that his kids thought he was one.
