To make a film and to sell it to the distributors you need a name.
In the South, it is different, they have a audience that is literate.
You get an image after you act in a film, but it is not necessary that you last long because of that image.
It gets tiring, doing the same thing everyday.
There are two types of films - one made by the big-time producers, the other is low budget stuff made by some producers who make films for the heck of it, they complete their films for small amounts, sell it at low costs with almost no publicity.
In the industry, you do need some ethics - if one film does well, then thousands get work and money comes back to the industry. I guess the bottomline is, if there are two versions, then the better one will click.
