An actor is only a part of the film, not the whole, and very often, he is moulded by the director. That is why a good director can make so much difference to a film.

Krishna Vamsi is a very good director.

I've been directed by other actors, and being an actor doesn't make you a good director.

Matching character and actor is what a good director does.

If you do well as an actor, a good director will pick up on it, and keep it in the film.

A good project but a poor director will always make a mediocre film, but an average script and good director can make a good film, as he will put in everything to make the film look good.
