You do realize that you say that you are not influenced by Bollywood movies but the comment you refer to here references Bollywood movies as sources, right?
I don’t buy the argument that mafia or middle eastern emigre have influenced these potrayals in Tamil cinema since the 70s and 80s. It’s the local politics that did. Maybe there’s merit to the argument about Hindi films (I don’t know), but not Tamil.
You couldn’t be more mistaken if you confuse the South Indian film industry (then centered around Madras/Chennai) with the Hindi film industry (Bollywood, centered in Bombay/Mumbai).
